How To Learn Formal Punishment

Abstract

The unit of integer multiplication includes four contents: one is the operation properties of powers; the second is the multiplication of monomials; the third is the multiplication of monomials and polynomials; the fourth is the multiplication of polynomials. According to the rule of polynomial mining method, the multiplication of polynomials is actually transformed into multiplication of monomial; and the multiplication of monomial is essentially transformed into multiplication of numbers with the same base. Therefore, when learning the unit of multiplication of integers, be sure to clarify the following two issues: 1. The internal connection between the multiplication of monomials and the multiplication of powers of the same base The powers of the same letters are multiplied separately, and for the powers of letters contained in only one monomial, it is used as a factor of the product. It can be seen from this that the multiplication of monomials actually does three things: first, multiplying coefficients; second, multiplying powers of the same base; Example 1 Calculation: Solve the original formula = [(-2
