Homework Help

I've stared high school this year, and I need help with Maths homework- I don't know what half the questions mean, and it's piling up on my bedroom desk like dust! I spend hours trying to work it out, only to fail.

What's algebra? I need some kind soul to explain to me what algebra is A.S.A.P!

The algebra ones. Any other questions are fine.

Here's one of them-

Simplify j x j x j

Re: Homework Help

Whats the question wants you to do there, is to put it into index notation.

j×j×j = j³

index notation is a short hand as far as you need to be concerned at the moment so that you can write how many times the number is multipled with itself with a single number rather than having to write it all out.

so x² - means you have x times x.
y[sup]5[/sup] means y×y×y×y×y

etc.
