It's meeeeeeeee. . . againnnn

In this section of Math, I found quite a lot of things interesting. However, one thing that has stuck with me was how you calculate the HST in the Atlantic Provinces.

Step 1: Look at the question. Does it have any Discounts or Other Items (More than one)

What is the total cost, including tax, of the socks and underwear, if the socks are $8.49 and the underwear is $14.88? There is a 20% discount on the items as well.

Step 2: If there are more than one item, add the items together. (If not, ignore this step)

$8.49 + $14.88 = $23.37

Step 3: If there is a discount, multiply the decimal form of the discount by the cost of the item(s), then subtract it from the cost of the item(s). (If no discount, ignore this step)

20% = 20 / 100 = 0.20

$23.37 x 0.20 = $4.67

$23.37 - $4.67 = $18.70

Step 4: Take the Sale Price (Cost after Discount) and multiply it by the decimal form of the HST.

14% = 14 / 100 = 0.14

$18.70 x 0.14 = $2.62

Step 5: Take the Tax and the Sale Price and add the two together. It will give you the Total Cost of the item.

$18.70 + $2.62 = $21.32

Step 6: You are completely done the question and you got very pricey socks and underwear ;) (But Holy God, that must be some pretty good socks and underwear)

Remember that if you are finding PST and GST, DON'T combine the two taxes when you calculate them. LEAVE THEM SEPARATED OR CONCEQUENCES WILL BE WAITING.

Remember to study and then we can all have a Britney Spears party =O If you don't study, cellulite will haunt you forever =OO

Consumer Decisions

I learned a lot in this unit. This unit helped me gained more knowledge about taxes and sales. In real life, my mom asked me how much this jacket at GAP was. I told her the right amount with the 25% off sale and the PST and GST. When we went to the cashier, I was right. =) I felt so proud of myself.

Before I never knew about how to do all these taxes and sales. But I'm so happy I learned about it. This unit really helps me a lot especially in real life.

We learned about finding the unit price of one. Like for example,

At a fruit and vegetable stand, a dozen apples sells for $2.50. What is the price of one apple?

$2.50 / 12 = $0.21

So the unit price of one apple is $0.21

Then we learned about GST, PST, HST.

GST stands for Goods and Services Tax

PST stands for Provincial Sales Tax

HST stands for Harmonized Sales Tax. Harmonized Sales Tax is a combination of federal and provincial tax.

Here is an example of how to find GST and PST.

A customer purchases a new suit. The price of the suit is $285.00. What is the cost to the customer after GST and PST are added? The suit is purchased in Ontario.

Price of suit is $285.00

Now find GST and PST by converting the percent to decimal place. A reminder that PST in Ontario is 8%

GST - 6% / 100 = 0.06

PST - 8% / 100 = 0.08

Now multiply the price of the suit with the GST and then PST.

GST - $285.00 * 0.06 = $17.10

PST - $285.00 * 0.08 = $22.80

Now add the taxes together.

$17.10 + $22.80 = $39.90

Now add the price of the suit and the total taxes.

$285.00 + $39.90 = $ 324.90

And now, your done =)

Now here is an example of calculating HST.

Paul went to an electronic store and bought a CD player advertized at $450.00, a set of speakers at $235.00, and a portable telephone at $189.00. How much did he have to pay altogether including taxes? He bought these items in Nova Scotia.

Add all the prices together first.

$450.00 + $235.00 + $189.00 = $874.00

Now find HST of the total price of all the items that is being bought. HST in Nova Scotia is 14%

HST - $874.00 * 0.14 = $122.36

Add the total price of the items being bought and HST.

$874.00 + $122.36 = $996.36

Et Votre Fait! Yay! ( And Your Done! Yay! ) Hehe.

We also learned about the golden ratio.

BLOGGING ON BLOGGING

What I learned in this unit was that spreadsheets is an easy way to use formulas, and organize numbers. I learned that spreadsheets have labels and different types of values. Not only could we put numbersand the different equations but also, we can use Formulas to resolveeach cell. I also learned different types of math tricks in mental mathsuch as when a number is multiplied by 9 you use an easier trick by comparing it by 10.

Examples For Forumlas :

=SUM (B4*B5)
=AVERAGE (D6*D7)

[ ! ] BLOGGING ON BLOGGING

I thought that our last unit on spreadsheets was fairly simple. I was absent the day our class started the unit, so the next day when we were doing our mental math about spreadsheets, i was lost. After we reviewed the answers, i understood almost every concept. You don't need to know much about spreadsheets, to know how to do one. All you need to know, basically, is what a label is, what a formula is, and what a value is.

A label usually consists of ONLY letters in a cell. A formula is an equation beginning with an equal sign (very important), and a value is content in a cell that consists of nothing other than numbers. Along with this, you're also going to have to know how to identify cells. Cells are the little boxes that make up the spreadsheet.

Along the top of the spreadsheets are letters of the alphabet, and along the left-hand side are numbers. The proper way to identify a cell is to first find the column in which the cell is in, go all the way to the top, and remember the letter. Then find the row in which the cell is located, go all the way to the left, and remember the number. Then put the two together; letter first, number comes after.

Using the spreadsheet above as a reference, this is how you'd determine which cell it is. The highlighted box is under the "B" column, and located in the "2" row, therefore it is cell "B2".

When you know which cell you're supposed to put content in, then its pretty straight forward. If you're typing in a label, you should type NOTHING other than letters or words, with the acception of dates and such. If you're typing in a formula, letters and numbers are allowed, but you MUST remember to place an equal sign (=) before it, or it won't work the way it should. If you were to type in a value, there should be NOTHING but numbers in that cell.

When you put a label into your spreadsheet, it should automatically align to the left of the cell, unless it is further formatted. Opposite of labels, values are automatically aligned to the right of the cell, again, unless it is further formatted. Formulas are similar to labels, they are aligned to the left, and then automatically calculated to show the answer. You'll find that when you type the formula in, the answer will show up in the cell, but in the textbox, the formula is still there.

Speaking of formulas, there are a variety of formulas that are already there for you to use. You can find them all listed under the 'formulas' tab just along the top of the actual spreadsheet. Not all spreadsheet programs are the same, so you might have to search for a button that says 'formulas'. Formulas make spreadsheets all the more easier to work with, because it does all you're calculations for you automatically, the only thing you have to do is make sure the formula that you put in is correct, and that you didn't leave out the equal sign.

Examples of commonly used formulas are:
[ & ] = SUM(A2:G2) , OR , = SUM(A2+B2+C2+D2+E2+F2+G2)
... .... > to add cell values together .
[ & ] = A2*B2
..... .. > to multiply two cells together .
[ & ] = SUM(A2:A7)/2
... .... > to add multiple cells together , then divide by two .
[ & ] = AVERAGE(C2:C9)
....... > to find the average of multiple cells .

Spreadsheets are a good way to keep track of everything, especially when it comes to banking. Its easy to understand, quick to do, simple to access, and a big plus, no paper work OR self calculating!

[ ! ] GOOD LUCK ON THE TEST :)

In our last lesson, i learn a lot of things about spreadsheets. I dont know before how do spreadsheet but thanks to Mr. Kuropatwa, i know now how to make an spreadsheet on my own.
Spreadsheet contains a LABELS and VALUES. Before we put anything in the spreadsheet, we must first READ and FOLLOW the directions carefully because if we dont, everything will be mess up. And if we want to put a formula, always remember that always put an EQUAL SIGN because if we dont, the answer not gonna show up. For example, =sum(A2,A3),we can do this too, =A2+A3, this formula are both the same.
About the tricks too in mental math like how to solve 9 multiply into other number like 42. There's an easy way to solve this without using a calculator. this is how it is,

9x42=378

instead we multiply 9 to 42, we multiply 42 to 10 because 9 is close to 10 and 10 is easy to multiply to 42, just put zero after the number 42 then we get 420

10x42=420

then, we subtract 420 to 42 because we only need nine 42 and we multiply it in 10 so we must take one 42 in 420 and we get 387, and that's the answer.

420-42= 378

Its amazing that we are learning this unit because some other young teenager like us dont go to school. So dont waste time, learning everything makes a big changes in our life.

Goodluck in the test,,,,,

For the past few weeks, we've been learning about spreadsheets. There are different kinds of spreadsheets and they all work differently. It is very important that you follow the instructions carefully, otherwise you won't get the answer you want.

We learned that a cell can contain a label, value, or formula.

A cell that contains words is called a label.
A cell that contains numbers is called a value.
In order for it to be considered a formula, it MUST include an = sign (equal sign).

Some of you may have found this unit pretty easy, while the others found it pretty difficult. However, don't forget to STUDY for the math test tomorrow! Goodluck everyone.

It's Jaaaaaaames

In this section of Math, I found quite a lot of things interesting. However, one thing that stayed with me, was the trick of multiplying by 9. It helped me in a lot of places.

Step 1: Look at the equation. 14 x 9 = ?

Step 2: To multiply them together, multiply by 10. (Which is much easier) 14 x 10 = ?

Step 3: Solve the equation with the 10. 14 x 10 = 140

Step 4: Take the product and minus ONE of the numbers you used in the equation (NOT the 9 or 10). You want to do this, because you wanted 9 groups of that number, NOT 10. 140 - 14 = ?

Step 5: Solve the equation, once again. 140 - 14 = 126

Step 6: Dance around in circles, because you are done!

That is what I think helped me the most in this part of Math. Remember to study! You don't want to become some poor bum on the street, begging for money or trying to buy underwear, because you don't have any. A healthy mind, is a good mind!

Hello, Its me Joyce.

During this past few weeks I have learned alot about spreadsheets and the different kinds of spreadsheets I never knew before.

When doing spreadsheets you always have to read the directions very carefully. If you don't, it won't work.

When you type in a formula, we always have to have an "=" sign (equal sign). If there isn't a equal sign, IT ISN'T A FORMULA, it would be called a value.

A Label is a cell with words and a Value is a cell with numbers.

We looked at google spreadsheets and pbwiki spreadsheets.

This is what I learned in this unit =)

Good Luck on the test everyone =) and take your time =)

Always Smile,
Joyce

This is my Blogging on Blogging. during this past month i had learn So many things that i never even thought about. Like a new way of multiplying. In stead of......Pressing on your caclulator 34x36=1224 u can do it this way..

Example: take the two numbers that are the same from each digit. Witch is 3. Add one of them to make it turn to 4. so now you have 3x4 now multiply that together to get 12. then you take the 4 and the 6 that was left over then multiply that together and you get 24. So now you got the answer to the multiplication question. Its 1224 =D

34x36

3 x add one to the three = 4

3 x 4= 12

take the left overs

4 x 6 = 24

Now put it together

1224 =D

That was a new multiplication problem that i learn in Class and theres lots more.
In our current assignment spreadsheets. I learned that this symbol ( ^ ) was Exponent on the keyboard and this( * ) was Multiplication and( / )was Division. Well good luck to everyone on the spreadsheets test and hope you all do well. :D

Blogging on Blagging

This is my Blogging on Bogging, in our last lesson about wages and salaries; I learn a lot of things. for example: how much money a worker earn if she/hi work in this hours: M-9, T-9, W-8, TH-7, F-10 and his/her wages per hour is $12.00

Solution:

* add all the hours
9+9+8+7+10 = 43 hours
* multiply the total hours to the wages per hour
$12.00x43 hours=$516.00
then the total salaries that the worker eared is $516.00

This lesson in wage and salaries is really gonna help us in our day to day especially the working student.

Hello, sorry if i misspelt some words, i can't type on this computer well. Its slow, so anyways.

Everything we've learned about wages and salaries are kind of easy to me.

Finding the gross pay by multiplying how many hours you worked and your regular hourly pay.

Gross pay = (Regular Hourly Pay) (Hours you worked)

Ex.

Gross pay = ($9.00) (40) = $ 360.00

Then it gets more specific if you worked more hours than usual. Then you have to figure out their overtime hours, then their overtime pay. After you figure out those two, then you have to find your regular hours and your regular pay. After all of that, you add the overtime pay and the regular pay.

Step 1
Add all the hours together
Step 2
Figure out your overtime hours (Subtract total hours by your regular hours)
Step 3
Overtime pay = (wage)(Overtime hours)(overtime rate)
Step 3
Regular pay = (wage)(regular hour)
Step 4
Gross Pay = Overtime pay + Regular Pay

Ex.
Chang M.
M-10 T-7 W-8 TH-8.5 F-9
Hourly Wage $7.65
Earns time and a half if they work more than 40 hours.

1. 10+7+8+8.5+9 = 42.5 of hours

2. 42.5 - 40 = 2. 5 overtime hours

3. ($7.65) (2.5) (1.5) = $28.69 overtime pay

4. ($7.65) (40) = $306.00 regular pay

5. $28.69 + 306.00 = $334.69 Gross pay

Pretty simple right? Sometimes its 'double pay' instead of 'time and a half'. Just read questions carefully.

Then we learned about using timecards. The first time, i had a difficult time, but i understood after one whole class and did the questions that were from homework and the example from the smartboard.

Sometimes when your a minute late to work, you get 1 quarter(.25) taken away from your pay. Also, pretend your late 16 minutes, then it would be half (.5) taken away. And so on..

I found it alot easier if you keep practicing on the questions that you have most difficult. For me, I'm still rusty on my timecards. But if i keep practicing the questions all over. It would be easy for me at the end.

Remember everyone, do your homework. =)
Also! Good Luck on the test =)

I thought our last unit on "wages and salaries", was basically knowing how to multiply numbers together to get a final answer. At first, i found it confusing to figure out the gross pay after someone has worked overtime because of their overtime rate, which was either 1.5 (time and a half) or 2 (double time), depending on how much their employer pays them for working extra hours. To me it was simple to calculate the gross pay after i memorized a formula for each scenario.

GROSS PAY ( without overtime ) = total hours x hourly rate
GROSS PAY ( OT - time & a half ) = total hours x hourly rate x 1.5
GROSS PAY ( OT - double time ) = total hours x hourly rate x 2

In the beginning, i kept forgetting to multiply the total hours and the hourly rate by either 1.5 or 2, to get the total pay or gross pay including overtime pay, but after practicing and doing my homework, i got the hang of it. Something i found difficult was calculating time on time cards, and i don't think i'm the only one. I think a few of us had a hard time, 'cause we were used to calculating from 100 instead of 60. I had no problems with hours that ended in 00, 15, 30, or 45, what i had trouble with was hours that started or ended in odd numbers like 07, or 39 for example, but after Mr. K. did a few questions with us in class and showed us multiple ways to find the total hours, i understood it better and found it easier to do. The strategy i found easiest to use is when you begin with the starting time, find out how many minutes it is until the following hour, then use the following hour, and figure out how many hours is between it and the last hour worked, then i take the last hour and find how much time is between it and the last minute worked.
FOR EXAMPLE:
If someone works from 8:07 AM to 11:59 AM, I'd find out the answer like this..

8:07 AM - 9:00 AM = 53 mins.
9:00 AM - 11:00 AM = 2 hrs.
11:00 AM - 11:59 AM = 59mins.

...53 mins
...02 hrs
+ 59 mins
02 hrs & 112 mins

since 112 mins. is more than an hour, you deduct 60 (an hour) from it, and get 52 remaining minutes, and since you subtracted 60 mins from 112 mins, don't forget to add that 1 hr to the 2 hrs you already had. Thus, our answer becomes 3 hrs & 52 mins, if I'm not mistaken.

This is my BOB. I'm not sure whether we're supposed to answer all the questions or not, so here I go. I think everyone will agree with me when I say that the rapid math tricks we've learned have made math a lot easier. Knowing me, I am not good at mental math but thankfully Mr.Kuropatwa taught us the 'shortcut'. One of the things I found difficult at the beginning was keeping "track of time" only because I wasn't sure what it meant by "quarter" of an hour and so forth. I get it now because I kind of looked at it the way I would look at money, because a quarter of a dollar is $0.75, and a quarter of an hour is .75 also. This is the end of my blog, enjoy!

Time Card

In this lesson I found that I can use this in my daily life, in my future. I can keep track in my working hours by my own w/o asking any help from my co-workers, when I have doubt in my working hours if they make mistakes.....

Blogging on Blogging

In the lesson, Wages and Salaries, I have learned quite a bit of things I never knew before. "Multiplying Teens" was one of the tricks that interested me. I didn't know that the answer could be found in the question, which was pretty cool. One part of this lesson I found confusing was figuring out the hours a person worked, if the time wasn't precise. But, we worked more on this in class and I could say I improved on it. I feel that I have learned a lot in this lesson, but, I could still do much better.

Blogging On Blogging AKA BOB

We were talking about exactly what sort of post you're supposed to make to get that one blogging mark on your test. The kind of post I'd like you to make should have one or more of these characteristics:

Write about what you understand the least in the unit so far; your personal "Muddiest Point."

A reflection on a particular class.

A reflective comment on your progress in the course.

A comment on something that you've learned that you thought was "cool".

A comment about something that you found very hard to understand but now you get it! Describe what sparked that "moment of clarity" and what it felt like.

Have you come across something we discussed in class out there in the "real world" or another class? Describe the connection you made.

Your posts do not have to be long. I'm far more interested in the quality of what you write rather than the quantity.

Make certain you always use 3 labels on your post: [your name], [unit tag], BOB

When you share where you are in your learning a few days before the unit test I can address those issues in class so, hopefully, you will get much more than one extra mark on the test. ;-)

Happy Blogging!

Wages and Salaries,Hours and Minutes

In our lesson Wages and Salaries, i learn a lot of things that gonna help me when i'm going to get a job.I know now how to get how much money i will earn if i work from this hour and end in this hour,coz some company are not honest to their employee.In finding hours and minutes, it help me too when i'm going to get a job.I learn now how to get the exact hours and minutes if i work from this hour and end in this hour, coz i said before that not all company are honest to their workers. In mental math, i learn a lot lot of things and "tactics" to solve a problem without using a calculator.Its really improve my ability to solve a problem.I feel great that i learn this well.

I found that the Multiplying Teens were useful to me. In Science, I had to multiply a few numbers with teens in them to find the total number of atoms or something. It was good that I finished that faster, than the other people who were using a calculator to find that answer. But the point is, I found the Multiplying Teens trick was really useful to me. It not only taught me something new, but it helped me in my other class.

(I don't know if I did this right or not)
