If the additive inverse of 'b' is 'a' then
- ab=1
- a=b
- a+b=0
- a-b=0
Explanation
The additive inverse of " b" is " a "
To find :
(A) ab = 1
(B) a = b
(C) a + b = 0
(D) a - b = 0
Solution :
Step 1
Define the additive inverse of a 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
Step 2
Choose the correct option
Here it is given that the additive inverse of " b" is " a "
So by the given condition
a + b = 0 = b + a
Hence a + b = 0
