How do you do subtraction without regrouping?

Subtracting 3 Digit Numbers without Regrouping We always start subtracting in the ones place. Since there is no regrouping, our top number will always be larger than our bottom number. First, in the ones place, we would subtract 5 – 3 = 2. Next, in the tens place, we would subtract 4 – 1 = 3.
