Question 161082: Hi I need help with this:
can the opposite of (-a) be a negative number? why?

Sure. If "a" is negative to start with, then -a is positive. And -(-a) is just a. Which is negative.
To be concrete, start with the number -5. Then -(-5) is 5. And the 'opposite' of 5 is -5 - which was where you started
