Math Problem Statement

-4(-7 + 5)(-2) - |-2 - 5|

Solution

Let's solve the expression step by step:

Expression:

4(7+5)(2)25-4(-7 + 5)(-2) - |-2 - 5|

Step 1: Simplify inside the parentheses and absolute value

First, simplify (7+5)(-7 + 5) and (25)(-2 - 5): 7+5=2-7 + 5 = -2 25=7-2 - 5 = -7

Now, substitute these back into the expression: 4(2)(2)7-4(-2)(-2) - |-7|

Step 2: Evaluate absolute value and multiplication

The absolute value of 7-7 is 7, and now we evaluate the multiplication: 4(2)(2)=4×(2)×(2)-4(-2)(-2) = -4 \times (-2) \times (-2)

Start with: 4×(2)=8-4 \times (-2) = 8 Then: 8×(2)=168 \times (-2) = -16

Now substitute back: 167-16 - 7

Step 3: Final subtraction

167=23-16 - 7 = -23

Final Answer:

23-23
