Answer:
28
Step-by-step explanation:
According to Order of Operations rules, we must multiply here before adding or subtracting.
In 7 +6 - 9(-2) + (-3) the very first thing we must do is to evaluate the product -9(-2). This comes out to 18, so now we have:
7+6 + 18 +(-3).
Next, remove the remaining parentheses, obtaining:
7 + 6 + 18 - 3, or
13 + 15 = 28
=13+18-3
=31-3
=28
the answer is 28
