Question 368753: What number is n in this addition inverse operation problem? 12 + n
Answer by neatmath(302) (Show Source): You can put this solution on YOUR website!
The inverse number for addition is the opposite number (or negative number).
The number plus its additive inverse always equals zero!
In this case 12+n, you just need to set this equal to zero to find the inverse number.
12+n=0
n=-12
Therefore, the additive inverse of 12 is -12.
You can also just multiply the number by -1 to find the additive inverse.
Thus, the additive inverse of -5 is just 5
which is -5*(-1)
I hope this helps!
