Q2 of 51 Page 19

Write the additive and the multiplicative inverses of the following.

−1

Additive inverse, -1

Multiplication inverse, 1


Explanation:- When a number is added to its additive inverse, the result is zero. When a number is multiplied to its multiplicative inverse, the result is 1.


Solving for additive inverse:-


(-1) + x = 0


(add 1 to both sides)


X = 1


Solving for the multiplicative inverse:-


(-1)X = 1


(dividing both sides by(-1))


X = 1
