IN MATH: 1. n. an operation which undoes another operation. EX. Addition of 5 undoes subtraction of 5.

	addition				subtraction
	subtraction				addition
	multiplication			division
	squaring				square-rooting
	raising to the second power	raising to the 1/2 power
	taking the opposite			taking the opposite
	taking the reciprocal		taking the reciprocal

2. n. for addition, the opposite; for multiplication, the reciprocal: for an operation with an identity, one number of a pair of numbers whose operation together results in the identity. FOR EXAMPLE:

     number, operation, inverse, identity
       5       +         -5    =  0
       -5       +         5    =  0
       5      times      1/5   is 1
       1/5      times      5   is 1
