Question

The expression 15 – 3 [2 +6(-3)]

simplifies to
A.
-45
B. -33
C. 63
D. 192

Answer 1

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 :)

Answer 2

63

Explanation:

6*(-3)= -18

2+(-18)= -16

3*(-16)= -48

15- -48= 63
