Anyone know why don't exponents change with addition and subtraction and the opposite with division and multiplication?
I know how to do the equations and everything, but I really want to know WHY.
My thanks goes to anyone who can help!
If you don't know what I mean...
I was looking for an explanation on why 2x^2+2x^2 = 4x^2
whereas 2x^2 multiplied by 2x^2 = 4x^4
