Answer 2

SOLUTION

TO DETERMINE

The opposite number of - 84

EVALUATION

First we know what is opposite number

For any given number the opposite number of the number is the additive inverse of the number

We know that 0 is the additive identity

Let N be any number and M be the additive inverse of N

So by the property of additive inverse

N + M = 0 = M + N

Now N + M = 0 gives M = - N

More precisely for any given number the additive inverse is the number that when added to the given number will result zero

So from above we can conclude that additive inverse of N is - N

Here the given number is - 87

Hence the required opposite number of - 84

= Additive inverse of - 84

= - ( - 84 )

= + 84

FINAL ANSWER

The opposite number of - 84 is 84
