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
