Verify Subtraction by Using Addition | Utilize Addition for Subtraction Verification

Introduction:

Subtraction can be checked by adding the difference to the smaller number. This method is effective even with regrouping. For example, when subtracting 48 from 82, the difference is 34. By adding the difference (34) to the subtrahend (48), the sum (82) is obtained, confirming the correctness of the subtraction. More examples and practice questions are provided.

How to Check Subtraction Using Addition: A Simple Method

Subtraction is a fundamental operation in mathematics. Sometimes, it can be tricky to determine if a subtraction problem is correct. However, there is a simple method to check subtraction using addition. Let’s explore how this method works.

The Addition Method for Checking Subtraction

To check subtraction using addition, you can follow these steps:

Step 1: Set up the Subtraction Problem

Start by setting up the subtraction problem with the minuend (the number being subtracted from) and the subtrahend (the number being subtracted).

Example:

82 – 48

Step 2: Subtract the Numbers

Perform the subtraction to find the difference between the minuend and subtrahend.

Solution:

82 – 48 = 34

Step 3: Add the Difference to the Smaller Number

Add the difference to the subtrahend (the smaller number).

Example:

34 + 48 = 82

Step 4: Compare the Sum to the Minuend

If the sum of the difference and the subtrahend equals the minuend (the larger number), then the subtraction is correct.

Conclusion:

Since the sum of 34 and 48 is equal to 82 (the minuend), we can say that the subtraction is correct!

Examples of Checking Subtraction using Addition

Example 1: 82 – 48

Solution:

We subtract 48 from 82:

82 – 48 = 34

When we add the difference (34) to the subtrahend (48), the sum is equal to the minuend (82). Therefore, the subtraction is correct.

Example 2: 59 – 24

Solution:

We subtract 24 from 59:

59 – 24 = 35

When we add the difference (35) to the subtrahend (24), the sum is equal to the minuend (59). Hence, the subtraction is correct.

   Subtraction using Addition | Frequently Asked Questions

   FAQs Section

   Q: How can addition be used to check subtraction?

   A: Addition can be used to check subtraction by performing the reverse operation. When you subtract one number from another, you can add the difference back to the subtrahend to verify if you get the original minuend. If they match, the subtraction is correct.
   Q: What is the benefit of using addition to check subtraction?

   A: Using addition to check subtraction helps in identifying any errors made during the subtraction process. It provides a reliable method to confirm the accuracy of the calculation.
   Q: Can addition always be used to check subtraction?

   A: Yes, addition can always be used to check subtraction. As long as the subtraction was performed correctly, adding the difference back to the subtrahend will yield the same minuend.
   Q: Are there any specific steps to follow when using addition to check subtraction?

   A: To use addition to check subtraction, subtract one number from another as you normally would. Then, add the difference back to the subtrahend. If the sum obtained matches the minuend, the subtraction is accurate.
   Q: Is checking subtraction with addition a widely used technique?

   A: Yes, checking subtraction with addition is commonly taught in mathematics education to ensure students grasp the concept of subtraction accuracy and verification.
