OMG, this thread gives me a headache
I CANNOT STAND MATH! (I suck at it)

Only when you're working on parallel universesI quit math after they introduced imaginary numbers. I kept arguing with the teacher saying that if the numbers are only imaginary then how can we know the result is real???
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.
Well put! I aced calculus, so read on only if you'd like.Originally Posted by kluchetta
Because Algebra is about finding the unknown. The unknown is x.
Amy, if you ever need in person help remember I'm only a 20minute drive away!Originally Posted by luvmycat1
I'd rather x remain a mystery.Unfortunately I have to take Basic Algebra for college and I stink so bad I have to take a refresher course in Pre Algebra.

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.

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.
In that case, let's throw out geometry and trigonometry too.Originally Posted by luvmycat1
I don't understand why they have to take simple addition, subtraction, multiplication, and division; throw it together in a weird way and make you break it down in to steps to solve it.What is the point of Algebra?
Hey I'm all for that.Originally Posted by Persi & Alley

My favorite is the quadratic formula!Originally Posted by Beck4582
I loved Algebra!! I can still recite the pathagoryan theorum sadly enough... What was AWFUL was trig!!! I never was good at that.
