Subtract $24 - (-15)$. \[$\square\$\]
Understanding the Concept of Subtracting Negative Numbers
When dealing with negative numbers, it's essential to understand the concept of subtracting them. In mathematics, subtracting a negative number is equivalent to adding its positive counterpart. This concept is crucial in solving various mathematical problems, including the one presented in this article.
The Rules of Subtracting Negative Numbers
To subtract a negative number, we need to follow a specific set of rules. The first rule is that subtracting a negative number is equivalent to adding its positive counterpart. This means that $a - (-b) = a + b$, where $a$ and $b$ are any real numbers.
Applying the Rules to the Given Problem
Now that we have a clear understanding of the rules of subtracting negative numbers, let's apply them to the given problem. The problem asks us to subtract $-15$ from $24$. Using the rules we learned earlier, we can rewrite this problem as $24 + 15$.
Solving the Problem
To solve the problem, we need to add $24$ and $15$. This can be done by simply adding the two numbers together.
Conclusion
In conclusion, subtracting a negative number is equivalent to adding its positive counterpart. By applying this rule to the given problem, we were able to rewrite it as $24 + 15$ and solve it by adding the two numbers together. The final answer to the problem is $39$.
