(a)
Since 2 in the hundreds place is not enough to subtract 5, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 5.
K - 1 - 2 = 2
1 + 2 + 2 =
5K =
5(b)
Since 2 in the hundreds place is not enough to subtract 5, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 2 so that the sum 12 can be used to subtract 5.
10 + 2 -
L = 5
12 - 5 =
7L =
7 Answer(s): (a) 5; (b) 7
