Other than that I use to love algebra. Math in general strengthens us our cognitive ability. For example the ability to get into a car and navigate ourselves around, find shortcuts etc. For example, without math, you wouldn't have the computer in front of you. Without 1s and 0s and having the ability to know 0,2,4,8,16,32,64, for RAM and such IT people would not exist.

It also has use with our bank accounts. Having algebra allows you to say to yourself: I can afford to put away $200 per month. I need to save $1500 for my Spring Break. How many months will it take to save this much?
So then 200 * x = 1500...so then x = 7.5 months.
Why the heck cant you just say 1500 Divided by 200 = 7.5?? I dont mind algebra but the way things are worded to make it harder is silly! When I was in my algebra classes I switched everything they gave me into the way I saw it! hence 200* x =1500, I know I can say 1500/200 =7.5!

Well put! I aced calculus, so read on only if you'd like.

You are not just doing arithmetic but solving for x. For example:

7x-5 = 15 + 4x -5
7x - 5 +5 = 15 + 4x
7x = 15 + 4x
7x - 4x = 15
3x = 15
x = 5

Here is an example of imaginary numbers and how they are used in the real world. It is really somewhat technical. I liked the snow plow example. It is really used in real life in electrical engineering and physics.

Nuh uh...might give me away!
Love love love Math, but I have a BA in English.


I am really enjoying this thread.

I remember trying to figure something out in Neopets. I wanted to know how many neopoints (currency) I needed in my bank account in order to get 10,000 neopoints back in daily interest (the interest is listed as yearly). I got excited just because I knew I needed formulas.

I figured I needed around 26 million neopoints (I'm halfway there!) to get 10,000 back in interest.

ERGGGGGGGGGGGGGGG Algebra was the worst math subject ever!!!!


want to know what my test score was in the end?






2%!!! i only had half a question right! and yes my teacher did give up on me after that score!

I have to say... I LOVE this thread! I'm a total math geek.

Unfortunately I have to take Basic Algebra for college and I stink so bad I have to take a refresher course in Pre Algebra.
Amy, if you ever need in person help remember I'm only a 20minute drive away!

I found a website last night that offered practice with these equations. It took me a minute to figure them out. It's really hard.

What is the point of Algebra?
In that case, let's throw out geometry and trigonometry too.

I love algebra. I still do the FOIL method for kicks.

ALgebra also helped with other math/classes (like Statistics) through school.

I had to take math through calculus for my major. If you need to take chemistry or physics you will use algebra constantly. I think a good base in algebra is as important as knowing how to write a good essay.

Algebra - my favourite subject. I would do all my homework and save Algebra for last because I loved doing it.

My take on it was that it made you think and figure things out which exercises those little grey cells.

I love, love, love algebra!
I was a Math major for 2 years in college. I love geometry and statistics also. Calculus wasn't my favorite, but it was Differential Equations that made me run screaming.
