Can You Subtract One Negative from Another to Turn It Into a Positive?

Understanding the rules of arithmetic, especially when dealing with negatives, can often lead to confusion. One common question is whether you can subtract one negative number from another to turn it into a positive. In this article, we will explore this concept through examples and explanations to clarify any doubts.

Introduction to Negative Subtraction

Subtraction of negative numbers might seem counterintuitive, but it is a fundamental part of arithmetic. When you subtract a negative number from another, you are essentially undoing the negative effect and moving towards a positive value.

Example 1: Subtraction of Negative Numbers

Let's consider the problem: -2 - (-3).

-2 - (-3) -2 3 1

In this example, subtracting -3 from -2 is the same as adding 3 to -2, which results in a positive 1.

Example 2: Subtraction with Multiple Negative Numbers

Another example to consider is: -5 - (-4).

-5 - (-4) -5 4 -1

Similarly, subtracting -4 from -5 is the same as adding 4 to -5, which results in a negative 1. Notice how the negative effect of the second number is reduced when subtracting a negative from a negative.

General Rule: Can You Subtract One Negative from Another?

Yes, you can subtract one negative from another. This is because subtracting a negative is the same as adding the positive counterpart of that number. The key is to understand that subtracting a negative number is not the same as performing a subtraction with two positive numbers. Here's a more general rule:

If a - b, then a - b > 0. It does not matter if one or both are negative.

Understanding the Concept

Let's break down the concept further with a few more examples:

Example 3: Adding More Positive Numbers

For example, if you have 5 - 6, you get a negative result:

5 - 6 -1

However, if you have -5 - (-4), you get a negative result:

-5 - (-4) -1

Solution 5 - 6 -1

Similarly, -5 - (-6) gives you a positive result:

-5 - (-6) 1

Conclusion: Can You Add 2 Negatives to Get Positive?

No, adding two negative numbers will always result in a negative number. However, subtracting one negative from another can indeed turn it into a positive, as demonstrated in the examples above.
