## Homework Statement

First, let me tell you a bit about myself. I did not do well in geometry and math in middle school, I was terrible at it. At high school, something changed and I took Algebra I. I was getting B's to high A's. I got awarded the rotary club award for student of the month, because of my grades at the time. I had a lot of problems in school with learning problems, so I decided to graduate from a charter school. I graduated and have been taking a long break, many years, I'd say at least 4 or 5 persuing other interests. I recently started some training in basic computer skills such as excel, powerpoint and word and am starting my internship this monday, 10 weeks, 2 hours a day, 2 days a week. After that I plan to get a job with basic clerical computer work, and study and go to college on the side with a pale grant. I have always enjoyed math immensly, and I got the book "calculus for dummies" and read it from cover to cover. The main thing was I could not do most of it like basic limits because I never learned how to factor.

I also skipped geometry and trigonmetry, as I just wanted to read out of pleasure. I enjoy reading about mathematics and solving problems. Recently when I was at computer school I picked up a GED book on factoring, hoping to finally learn it. I reviewed some algebra I hadn't done for years, and managed to get the factoring questions right. Needless to say I was happy with that. The main thing, I found out, was to find the greatest common factor of the terms and put that on the outside of the formula, then ask myself that number times "what" equals the outcome.

I do want to take some schooling in mathematics and perhaps engineering after I get really good. But I find myself not understand even the basic problems. I have a very good book (at least I think so) on algebra, it is called "Algebra, The easy way" and is presented in a story, which I find easier to learn on the most part, because it explains WHY things happen the way they do. However, I'm stuck on the first chapter! Here's the problem:

Verify the associative properties of addition and multiplication in the following cases. To do this, calculate the result of the expression in two different ways. (It does not say how)

For example,

3 x (4 x 5)= 3 x 20 = 60

(3 x 4) x 5= 12 x 5 = 60

## Homework Equations

Problem 1:

12 x 6 x 2

Problem 2:

11 x 5 x 16

Part 3:

In excerises 20-31, write formulas that perform the indicated functions. (In each case you will need to think of the appropriate letters to represent the quantities indicated)

20. Calculate your pay if you work

*h*hours in one week and are paid $5 per hour.

## The Attempt at a Solution

For the first 2 problems, I'm really at a lost here. I learned how to factor polynomials with algebra, but I can't figure out this! It must be really simple. If someone could please give me a tip or hint or how to solve them, it would be greatly appreciated!

On part 3, I used to be good at word problems, I guess I can try to solve this one!

Let h equal the number of hours worked in one week. Then,

$5/per hour x 7

*h*

Is this correct?

Thanks for helping me out, or giving me hints! I love this book and want to try and get back into math.
