This is a free lesson from our course in Algebra I

 This lesson is the introduction to the lesson which explains to you the basics of inverse operations.. This will help you understand and learn the inverse operation in Algebra. Simply put, if an operation reverses another operation, then it is an inverse operation. Let's take a general example,every day, you "perform an operation" of going from home to school. Its inverse is going from school to home. The same logic applies to inverse operation. If you start with 5, add 3 to get 8, then the inverse would be to subtract 3 from 8 go back to where you started, that is to 5. The lesson also explains the concepts of additive and multiplicative inverse. For example, two numbers are called multiplicative inverses or reciprocal of each other if their product is 1. a is the reciprocal of b, if a x b = 1.
