Answer:
C: 63
Explanation:
First we start by evaluating in the brackets [ ]
15 - 3 [2 + 6(-3)] in this problem we start with the parenthesis, 6(-3). This means 6x(-3)
So, 6x(-3)= (-18)
Now the question becomes
15 - 3 [2 + (-18)] We will continue evaluating the brackets:
To continue, the next step will be to add 2 and -18
2 + -18 = -16
Now the entire problem becomes:
15 - (3 x -16) and we finished the brackets so now we do 3 times -16 because the next step is 3[2+(-18)
So, 3 x -16 = -48, making the problem:
15 - (-48). When you're subtracting negatives, you're essentially getting rid of the negative and adding that negative number as a positive. So:
15 - (-48) = 63 :)
