CCSS.Math.Content.7.NS.A.2.a Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (-1)(-1) = 1 and the rules for multiplying signed numbers. Elimination Method (Systems of Linear Equations) The main concept behind the elimination method is to create terms with opposite coefficients because they cancel each other when added. In the end, we should deal with a simple linear equation to solve, like a one-step equation in or in .
