Answer 3

In the given expression, we have a combination of negative (-) and positive (+) signs. Let's break down each combination:

(-) : (+) = (-) When a negative sign is followed by a positive sign, the result is negative.

(+) : (+) = (+) When a positive sign is followed by another positive sign, the result remains positive.

Therefore, the combinations in the given expression can be simplified as follows:

(-) : (+) = (-) (+) : (+) = (+)

So the simplified expression would be: (-) : (+) = (-) (+) : (+) = (+)
