Understanding (-7)-(-5)
Subtracting a negative number is the same as adding its positive counterpart. This concept can be a bit tricky to grasp, but it's essential for understanding basic math. Let's break down how to solve (-7)-(-5).
The Concept of Double Negatives
In math, two negative signs next to each other cancel each other out. This is because subtracting a negative number is the same as adding its positive value.
Think of it like this: If you owe someone $5 (represented as -5), and then they take away that debt (represented as subtracting the negative), you are essentially gaining $5.
Solving (-7)-(-5)
Applying this concept to our problem, we can rewrite the equation:
(-7) - (-5) = (-7) + 5
Now, we have a simple addition problem.
(-7) + 5 = -2
In Conclusion
Therefore, (-7) - (-5) equals -2. Remember, subtracting a negative number is the same as adding its positive counterpart. This understanding will help you solve similar problems in the future.
