Is there anything else in mathematics that is opposite of each other that I should know about?
Thanks....

addition is the inverse operation of subtraction
multiplication is the inverse operation of division
squaring and square roots, etc
derivative is the inverse integral (integral function is an anti-derivative)
the inverse of f(x) is f^-1(y)
The logarithmic function is the inverse of the exponential function

Can you give an example of squaring and taking the square root?

Let me see if I can do it.

sqrt{16} = 4 because 4^2 = 16.
Also, sqrt{16} = -4 because (-4)^2 = 16.

Yes?
