Here we will learn about reciprocals, including the definition of reciprocal and how to find reciprocals. The reciprocal of a number is 1 divided by the number.

Every number has an opposite. In fact, every number has two opposites: the additive inverse and the reciprocal —or multiplicative inverse. Don't be intimidated by these technical-sounding names, though. Finding a number's opposites is actually pretty straightforward. The first type of opposite is the one you might be most familiar with: positive numbers and negative numbers. For example, the opposite of 4 is -4 , or negative four. On a number line, 4 and -4 are both the same distance from 0 , but they're on opposite sides.
