Product law: add the exponents together when multiplying the powers with the same base. Ex: NOTE: This operation can only be done if the base is the same!

Quotient law subtract the exponents when dividing the powers with the same base. Ex: NOTE: This operation can only be done if the base is the same!

Power of a power: keep the base and multiply the exponents. Ex: NOTE: Multiply the exponents, not add them!

Zero exponent law: Any power raised to an exponent of zero equals one. Ex: NOTE: No matter how big the number is, as long as it has zero as an exponent, it equals to one. Except

Negative exponents: To make an exponent positive, flip the base. Ex: NOTE: This does not change the sign of the base.

Multiplying Polynomials: In multiplying polynomials, you have to multiply the coefficients and add up the exponents of the variables with the same base. Ex:

Dividing polynomials: When dividing polynomials, you must divide the coefficients(if possible) and subtract the exponents of the variables with the same base. Ex:
