Three digit subtraction without borrowing
When you subtract without regrouping (borrowing), all of the numbers you're subtracting are smaller than the digits you're subtracting from.
In the column subtraction method it means than the upper digit is larger or equal than the digit below it.
Three digit subtraction with borrowing
Three digit subtraction with borrowing is used (in the column method) when the minuend (the number from which another is to be subtracted) is smaller than the subtrahend (the number to be subtracted from minued).
How to do three digit subtraction
For example, let’s take the problem: 747 - 489. Starting with the units (the right column), you can’t take 9 away from 7.
So, we have to borrow 1 from the tens column. We are now subtracting 9 from 17. It is 8.
We continue to subtract the tens column, the middle column in this case. Since, 1 ten is regrouped by ones column, so we will subtract 8 from 3 (4-1). It is not possible, so we borrow 1 from hundreds and will subtract 8 from 13. It is 5.
Finally, we subtract the hundreds column, the left one. We subtract 4 from 6 (7-1 because we borrowed 1 in the previous step). The result is: 6 - 4 = 2.
Subtraction 3 digit numbers
3 digit numbers are numbers that consist of 3 digits. They begin with 100 and end on 999. In our 3 digit subtraction game numbers are randomly generated in this range.
We use regrouping in subtraction problems when digits in the minuend are smaller than the digits in the same place in the subtrahend.
When subtracting three digit numbers 3 digit numbers we have to understand changing pattern in each of the digits of the hundredth place, ten's place, and unit's place, as we explained in the example above.
