It is a second operation that "undoes" the first.For example, the inverse of "add 2" is "subtract 2";the inverse of "divide by 7" is "multiply by 7";the inverse of "take the reciprocal" is "take the reciprocal".
The inverse function means the opposite calculation. The inverse function of "add 6" would be "subtract 6".
A number and its additive inverse add up to zero. If a number has no sign, add a "-" in front of it to get its additive inverse. The additive inverse of 5 is -5. The additive inverse of x is -x. If a number has a minus sign, take it away to get its additive inverse. The additive inverse of -10 is 10. The additive inverse of -y is y.
The multiplicative inverse is the negative of the reciprocal of the positive value. Thus the multiplicative inverse of -7 is -1/7.
It depends on whether you mean additive inverse or multiplicative inverse.
