(a)
Add 2 and 8 in the ones place and take the digit in the ones place from the answer.
2 + 8 = 1
0 B =
0(b)
Since 1 in the hundreds place is not enough to subtract 3, 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 3.
10 + 1 -
C = 3
11 - 3 =
8C =
8 Answer(s): (a) 0; (b) 8
