(a)
Since 3 in the hundreds place is not enough to subtract 8, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 9.
P - 1 - 2 = 6
1 + 2 + 6 =
9P =
9(b)
Since 3 in the hundreds place is not enough to subtract 8, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 3 so that the sum 13 can be used to subtract 8.
10 + 3 -
Q = 8
13 - 8 =
5Q =
5 Answer(s): (a) 9; (b) 5
