Doing the subtraction test is something that we should all know if we want to be sure that the operation we have just done is correct. This test is very simple, but we have to know how it works to be able to apply it correctly.

Therefore, in this article we teach you what a minuend, subtrahend and difference are, what the subtraction test is, how to do the subtraction test and you will also see step-by-step subtraction test exercises.

## Minuend, subtrahend and difference

He **minuend, subtrahend and difference** They are the parts of subtraction or subtraction. Knowing them well is essential to apply the subtraction test.

Let’s see what the parts of subtraction are:

**vertical subtraction**

**Horizontal subtraction**

minuend:

**He **Minuend is the number from which we are going to subtract some amount when subtracting. That is, the minuend is the number from which we are going to “remove”.

**Subtracting**:

**The subtrahend** It is the amount that we are going to remove or subtract from the minuend. The subtrahend is less than the minuend.

**Difference**:

**The difference** is the number resulting from performing the subtraction, that is, the difference is the result of the subtraction. In the subtraction algorithm, the subtrahend is subtracted (or removed) from the minuend, and the amount that remains is called the difference.

*Thanks to the following worksheet that we suggest, you will be able to discriminate the different terms of subtraction yourself:*

## What is the subtraction test?

The subtraction test is a procedure that is based on the subtraction algorithm to know if the result obtained is correct. This test is carried out using the relationship that exists between minuend, subtrahend and difference.

Let’s see how the subtraction test works:

As we explained in the previous section, the quantity called subtrahend is “removed” from the minuend and we are left with the difference.

If we use the inverse process we would have the minuend as a result, that is, by adding the difference with the subtrahend we obtain the minuend as a result.

Observe:

We can then say that the subtraction proof is based on this:

Subtraction test: yes to difference (D) we add the subtrahend (S) the result obtained is the minuend (M).

### How do you do the subtraction test?

After making a subtraction, one of the things we are most interested in knowing is if everything is correct. That is why in this section we tell you how to do the subtraction test.

To check if the result of a subtraction or subtraction is correct, we have to **add the subtrahend with the difference** And the result **must be equal to the minuend**. This is:

Difference + Subtracting = minuend

d + Yes = M

**Let’s look at an example with the following subtraction:**

**Subtraction**

**subtraction test**

The substraction **7,569 – 3,478 **has been resolved correctly, because when performing the verification it is true that **difference** **further** **subtracting** **is equal to** **minuend**.

**Let’s look at a second example in which the subtraction is solved incorrectly.**

**Subtraction**

**Subtraction Check**

In this example the **subtraction** was **resolved incorrectly **so the **difference** **further** he **subtracting** **No** **is equal to minuend. **

## Subtraction test exercises

In this section you will see subtraction test exercises solved step by step.

**Calculate the following subtractions and check the result of each one:**

to.

b.

**Answer:**

To answer exercise 1, we first solve the subtraction. Then, to check it, we are going to add the difference (result) with the subtrahend (number that we removed), and the result must be the minuend. Let’s see:

**Use what you know about the subtraction test to complete the following subtractions:**

to.

b.

**Answer:**

To find the number that we must enter to complete each subtraction we will rely on the subtraction test. Remember that **difference + subtrahend = minuend. **Following this we can rewrite the following:

to.

b.

Notice that we have applied the principle of the subtraction test. What we have now is to look for:

**A number that added to 6 is equal to 8:**

**And another number that added to 7 is equal to 12**

6 + 2 = 8

7 + 5 =12

to.
