Question

find the values of the letters in the following and give reason for the steps involved​

Answer 1

Answer:

1. A = 7 and B = 8.

2. A = 4, B = 3 and C = 1.

Step-by-step explanation:

1. when we add 7 to 5, we get 12, we write the two there, which is A.

when we do 4+3 and add the remaining 1  to it, we get B = 8

2. when we add 4 to 9 , we get 13. so, A = 4.

when we add 5+7 to the remaining 1, we get 13 which is CB. so, C = 1 and B = 3.
