Answer 2

It seems like you've provided a list of mathematical expressions, but the formatting is a bit unclear. It appears that you have provided three expressions in the form of "a - b", where "a" and "b" are numbers. If I've interpreted it correctly, here are the calculations for each expression:

1. $4 - (-3) = 4 + 3 = 7$
2. $7 - (-9) = 7 + 9 = 16$
3. $2 - (-6) = 2 + 6 = 8$

Please let me know if this is what you were looking for or if you had a different intention with your input.
