Find all the formulas of algebra in seventh grade mathematics. My monomial and polynomial degree math is not very good.
Algebraic expressions are divided into monomials and polynomials, where monomials are numbers * letters and polynomials are the sum of monomials.

2a to the power of m: A is the base, M is the exponent, the result is the power, and 2 is the coefficient.

Formula: M power of A * N power of A =(M+N)A power, the same base is multiplied, the base is unchanged, and the exponents are added.

(M power of A) = m*n power of A, with the same power, multiplied exponentially.

The m power of a/the n power of a = the (m-n) power of a, same base powers is multiplied, the base number is unchanged, and the exponent is subtracted.

Algebraic multiplication: take each monomial apart and multiply it by the coefficient, according to the above formula.

For example: 2a (cubic of B) * 7 (quadratic of A) B.

= 2 * A * (cubic of B) * 7 * (quadratic of A) * B.

= (2 * 7) * (quadratic of a * a) cubic of b * b)

=14 * the third power of a * the fourth power of b

Finally, remove the multiplication sign.
