Multiplying-dividing same number on both side of an equation

Algebra I: Multiplying-dividing same number on both side of an equation

This is a free lesson from our course in Algebra I


	This lesson explains the concept of the distributive property. It also explains how to solve an equation by simplifying both sides of the equation by clearing out any parentheses, and then combining like terms. When you distribute something, you give pieces of it to many different people. One example of distributing objects is handing out papers in class. In math, people usually talk about the distributive property of one operation over another. In general, if a = b, then ac = bc where c not equal to 0. If c = d, then c/e = d/e where e not equal to 0. Multiplying both sides of an equation by the same non zero number produces an equivalent equation. You may adapt this property to state that if you divide both sides of an equation by the same nonzero number, you obtain an equivalent equation. This fact follows from knowing that multiplying by the reciprocal of a number is the same thing as dividing by that number, c � 1/e is equivalent to c � e.

As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Algebra I by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards.
