(a)
Since 4 in the hundreds place is not enough to subtract 9, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 8.
J - 1 - 6 = 1
1 + 6 + 1 =
8J =
8(b)
Since 4 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 4 so that the sum 14 can be used to subtract 9.
10 + 4 -
K = 9
14 - 9 =
5K =
5 Answer(s): (a) 8; (b) 5
