Polynomial times polynomial: (a+b)(m+n)=am+am+bm+bn.

Multiplication with the same base power, constant base, exponential addition: a m * a n = a (m+n).

Power of product: (ab) n = a n * b n

Power: (a n) m = a Mn

Square difference formula: (a+b) (a-b) = a 2-b 2.

Complete square formula: (a+b) 2 = a 2+2ab+b 2.

(a-b)^2=a^2-2ab+b^2

Cubic sum formula: (a+b) (a 2-ab+b 2) = a 3+b 3.

Cubic difference formula: (a-b) (A 2+AB+B 2) = A 3-B.

This is nine.
