(a)
Add 9 and 5 in the ones place and take the digit in the ones place from the answer.
9 + 5 = 1
4 T =
4(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 -
U = 9
14 - 9 =
5U =
5 Answer(s): (a) 4; (b) 5
