3 Digit Subtraction with Regrouping Worksheets Made Easy

Mastering 3 Digit Subtraction with Regrouping Worksheets

Subtraction with regrouping is an essential math concept that can be challenging for many students. As they progress to higher grade levels, the complexity of subtraction problems increases, and regrouping becomes a crucial skill to master. In this article, we will explore the world of 3 digit subtraction with regrouping worksheets, providing you with a comprehensive guide to help your students or children become proficient in this math concept.

Understanding Regrouping in Subtraction

Regrouping in subtraction is a process where we borrow or regroup numbers from one place value to another to perform the subtraction. This concept is essential in 3 digit subtraction problems, where the minuend (the number being subtracted from) has multiple digits. To regroup, we need to understand the concept of place value, which refers to the value of a digit depending on its position in a number.

Place Value Review

Before diving into 3 digit subtraction with regrouping, let’s review the concept of place value. A 3 digit number has three place values: hundreds, tens, and ones.

• Hundreds place: The digit in the hundreds place represents the number of hundreds in the number.
• Tens place: The digit in the tens place represents the number of tens in the number.
• Ones place: The digit in the ones place represents the number of ones in the number.

Step-by-Step Guide to 3 Digit Subtraction with Regrouping

Now that we have reviewed place value, let’s move on to the step-by-step guide to 3 digit subtraction with regrouping.

📝 Note: The following steps are illustrated with examples to help you understand the process better.

• Step 1: Write the problem vertically, aligning the numbers according to their place value.
• Step 2: Subtract the ones place, starting from the right. If the minuend is less than the subtrahend, regroup from the tens place.
• Step 3: Regroup from the tens place by subtracting 1 from the tens digit and adding 10 to the ones digit.
• Step 4: Subtract the tens place, using the regrouped numbers.
• Step 5: Finally, subtract the hundreds place.

Example: 247 - 135

Let’s use the example 247 - 135 to illustrate the steps.

• Step 1: Write the problem vertically.
• Step 2: Subtract the ones place: 7 - 5 = 2
• Step 3: Subtract the tens place: 4 - 3 = 1 (no regrouping needed)
• Step 4: Subtract the hundreds place: 2 - 1 = 1
• Answer: 112
