simplify:
5-(-3)^2 -6
To simplify the expression 5 - (-3)^2 - 6, we need to follow the order of operations (also known as PEMDAS) to evaluate it step by step.
Step 1: Evaluate the exponent
(-3)^2 means (-3) multiplied by itself: (-3)(-3) = 9.
Now the expression becomes: 5 - 9 - 6.
Step 2: Perform subtraction from left to right
First, subtract 9 from 5: 5 - 9 = -4.
Now the expression becomes: -4 - 6.
Step 3: Subtract again
Subtract 6 from -4: -4 - 6 = -10.
Therefore, the simplified form of the expression 5 - (-3)^2 - 6 is -10.
