A 3-Digit Subtraction with Regrouping Worksheet typically contains a variety of subtraction problems that involve three-digit numbers. The objective is to practice the concept of regrouping, which is necessary when the number you are subtracting (subtrahend) is larger than the number from which you are subtracting (minuend) in a particular place value column. Regrouping involves “borrowing” a value from the next left column to make the minuend larger. The process begins from the rightmost column (ones place) and proceeds to the left. These worksheets are beneficial for building and reinforcing subtraction skills.
When you’re working with subtraction problems and the number in the top row (the minuend) is smaller than the number in the bottom row (the subtrahend), you have to “borrow” or “regroup” from the next column to the left. Here’s how you can do it.
For example, let’s take a look at this problem:
572
- 194- Start at the rightmost column (ones place): Compare the top number (2) with the bottom number (4). The top number is smaller, so we need to borrow.
- Move one column to the left (tens place): The number there is 7, which is greater than 1, so we can borrow from it. When we borrow, we take one ten, or 10 ones, from that column. So, the 7 becomes 6 and the 2 in the ones column becomes 12 (because we add the 10 we borrowed).
- Subtract in the ones place: Now we subtract the bottom number in the ones place (4) from the new top number (12). The answer is 8. We write this number down in our answer in the ones place.
- Subtract in the tens place: Next, we subtract the bottom number in the tens place (9) from the new top number (6). But, the top number is smaller again, so we need to borrow one more time.
- Move one column to the left (hundreds place): The number there is 5, which is greater than 1, so we can borrow from it. The 5 becomes 4 and the 6 in the tens column becomes 16 (because we add the 10 we borrowed).
- Subtract in the tens place again: Now we subtract the bottom number in the tens place (9) from the new top number (16). The answer is 7. We write this number down in our answer in the tens place.
- Subtract in the hundreds place: Finally, we subtract the bottom number in the hundreds place (1) from the new top number (4). The answer is 3. We write this number down in our answer in the hundreds place.
So, our final answer is:
572
- 194
------
378That’s the basic process for 3-digit subtraction with regrouping! Remember to start from the right and move to the left, borrowing from the next column whenever the top number is smaller than the bottom number. Practice this process using the problems in your worksheet and you’ll get the hang of it in no time!
