(a)
Add 3 and 8 in the ones place and take the digit in the ones place from the answer.
3 + 8 = 1
1 W =
1(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 -
X = 7
11 - 7 =
