This topic is locked. If you want to discuss this question please re-post it in the respective forum.

I'm a Comms major trying to make it big in business and naturally my experience with algebra, et al, has been slim to none for some time now. I'm trying to utilize any and all resources to learn, but i'm continually stumped by what some of the symbols mean for the online examples.

For example: a^2*b +b^2*c + c^2*a >= 3abc

I'm just starting out; so if someone would be kind enough to let me know what "^" stands for; as well as any other symbols like it, I would really appreciate it.

Hi Melie19 and welcome

^ is used to express an exponent. For example, 3^2 = 9.

>= means equal or greater

This is my suggestion only:

sq

e.g 4sq

It would be great to have this thread on the sticky board so that the newbies know what the symbols mean.

I agree, i've avoided this section because I had no idea how to read in-depth equations.

and for those of you other comms grads with no real memory of math, but a definite fear; here's a bit more on exponents:

The power to which a number or variable is raised (the exponent may be any real number).

from: http://www.nmlites.org/standards/math/glossary.html

use it for other math terms too; so far the easiest i've come across.

Hi Fig,

As a senior blogger here, do you know of a file that might have all the symbols defined? Especially in the instance of a forum like this? That way we can share the wealth and maximize GMAT club resources.

Let me know

No, I have never seen such file, sorry

Actually, the number of these symbols is not huge and the most important ones are probably already given to u now
