You're welcome.
To understand why 7 - (-1) equals 8, let's break it down step by step.
First, recall that subtracting a negative number is equivalent to adding its positive counterpart. So, the expression 7 - (-1) becomes 7 + 1.
Now, to solve the expression 7 + 1, you simply combine the numbers. Add 7 and 1 together, which gives you 8.
Therefore, 7 - (-1) equals 8.
To summarize:
- Subtracting a negative number is the same as adding its positive counterpart.
- In this case, 7 - (-1) becomes 7 + 1.
- Add the numbers together to get the final result, which is 8.
