I'm having trouble mainly with multiplying/dividing them.

When raising a power to a power, you multiply:

x^2^3 = x^6

When multiplying exponents with the same base, however, you add:

x^2 * x^3 = x^5

The same rule applies to division, same base = subtract.

x^2 / x^3 = x^(-1)

I'm not quite sure what you mean by dividing exponents, but recall that exponential fractions are handled in a specific manner:

x^(3/2) = SQRT(x)^3

When the problem is multplying exponets: example: (4^3)^3 you multiply the exponets. The answer is 4^9. Need more email me...I also know how to didivde them...

You should`ve mentioned your current school year, but I`ll give it a try. Here are the basic rules:
Adding:
exp(x)+exp(y) = same thing, we cannot combine them
same principle for subtractions
Mutliplying:
exp(y)*exp(x) = exp(x+y) so this is an interesting feature
Dividing:
exp(y)/exp(x) = exp(y-x)
taylor expansion:
exp(x) = 1+x+x^2/2!+x^3/3!+...
Imaginary exponentials:
exp(ix) = cos(x)+i*sin(x)

That`s pretty much all I can think of
Sorry, I thought you meant exponentials oups...
