Question

what value of A and B the expression A+B will equal to 0?
​

Answer 1

Answer:

A+B=0

A= - B

-B+B=0

Hence proved -

Answer 2

Given,

A+B is equal to zero.

To find,

The probable values of A and B.

Solution,

First of all, if both A and B,are zero.

Then, the value of A+B will be also zero.

A+B = 0+0 = 0

Secondly, if the values of A and B, are postive and negative numbers with same numerical value,then the value of A+B will be zero.

Example,

A = 2 and B = -2 (Positive and negative numbers, with same numerical value.)

A+B = 2-2 = 0

Hence,either A and B both will be zero or A and B are positive and negative numbers with same numerical value.
