Laws of sign numbers in multiplication
If you're going to multiply 2 LIKE SIGNS the answer would always be POSITIVE
example. positive x positive = positive
negative x negative = positive
While multiplying 2 UNLIKE SIGNS, the answer would always be NEGATIVE.
(The Laws of sign numbers in division is also the same in multiplication)
Laws of exponent in multiplication
If 2 base/variables are the same, copy it and add the exponents.
While in division
If the base/variables are the same, you will also copy it but you will subtract the exponents.
That's all what I know
