Simplify the expression:
15-3[2+6(-3)] show your work
We follow the order of operations (PEMDAS) to simplify the expression:
First, we simplify within the parentheses: 2 + 6(-3) = 2 + (-18) = -16.
Now, we have: 15 - 3(-16).
Next, we apply the distributive property: 15 - 3(-16) = 15 - (-48) = 15 + 48.
Now, we can add 15 and 48: 15 + 48 = 63.
Therefore, the simplified expression is 63.
To simplify the expression 15 - 3[2 + 6(-3)], let's first simplify the expression inside the parentheses:
6(-3) = -18
Now the expression becomes:
15 - 3[2 + (-18)]
Next, simplify the expression inside the brackets:
2 + (-18) = -16
Now the expression becomes:
15 - 3[-16]
Multiply -3 by -16:
-3 * -16 = 48
Now the expression becomes:
15 - 48
Subtract 48 from 15:
15 - 48 = -33
Therefore, the simplified expression is -33.
