Answer 2

It looks like you've provided some mathematical expressions, but it's not entirely clear what you're asking. The expressions you've written seem to be combinations of numbers and operators.

If you're looking for the results of these expressions, here they are:

1. +(-2) = -2
2. +(-3) = -3

In both cases, you have a positive sign followed by a negative number in parentheses. When you add a negative number, it's the same as subtracting the positive equivalent of that number. So, both expressions simply result in the negative value of the number inside the parentheses.
