Related concepts and laws you have mastered it? Integer addition and subtraction is a major seventh grade mathematics, but also junior high school algebraic knowledge of the beginning, we learn from the future multiplication and division, solving equations, solving inequality of the important basis for learning it Has an extraordinary meaning.Concept of concepts: related concepts algebra, monomial and. Its coefficients, times, polynomials and their times, terms, integers, the same items, etc. Clear rules: the relevant laws are the rules of merging similar items, the rules of bracketed rules, the integral addition and subtraction rules, and the polynomials. Application: Algebraic representation of the actual problem
