Final answer:
The expression -(-10) indicates changing the sign of -10, turning it into +10. This operation reflects the general rule that two negatives make a positive.
Step-by-step explanation:
To interpret the expression -(-10), you should view the negative signs as instructions to change the sign of the number that follows. In this case, the first negative sign indicates we will be changing the sign of what follows.
The number that follows is -10, which is negative.
When we change the sign of a negative number, it becomes positive.
Therefore, -(-10) is equal to +10.
This is similar to other mathematical operations where we change the sign before performing addition or multiplication,
for example, 5 - (+3) becomes 5 - 3, which equals 2, and 2 - (-6) becomes 2 + 6, which equals 8.
