# Find the value of A and B if

4 1 A

__+ B 4__

__5 1 2__

**Solution:**

From the __expression__ given we have:

A + 4 = number ending in 2

The smallest __number__ ending in 2 is 12. Therefore A = 8

1 will carry over and add to 41 to give 42.

Therefore,

42+9 = 51 Hence B = 9

**✦ Try This: **Find the value of A and B if

65 A

__+B 7__

__74 2__

From the expression given we have:

A + 7 = number ending in 2

The smallest number ending in 2 is 12. Therefore A = 5

1 will carry over and add to 65 to give 66.

Therefore,

66+18 = 84 Hence B = 8

Therefore A = 5 and B = 8
