This resource has been contributed by Winpossible, and can also be accessed on their website by clicking here - Getting started-Inverse operations.

It 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. 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·b = 1.

Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.

Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
