(a)
Add 9 and 7 in the ones place and take the digit in the ones place from the answer.
9 + 7 = 1
6 D =
6(b)
Since 1 in the hundreds place is not enough to subtract 7, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 1 so that the sum 11 can be used to subtract 7.
10 + 1 -
E = 7
11 - 7 =
