(a)
Add 7 and 4 in the ones place and take the digit in the ones place from the answer.
7 + 4 = 1
1 P =
1(b)
Since 6 in the hundreds place is not enough to subtract 9, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 6 so that the sum 16 can be used to subtract 9.
10 + 6 -
Q = 9
16 - 9 =
