Answer:
64
Step by step:
To determine how much you would subtract from the grouping, let's break down the expression step by step.
First, evaluate the expression inside the parentheses: (4 - 2)4.
This means subtract 2 from 4, which equals 2.
Then multiply the result by 4, which gives you 8.
Next, subtract 42 from 8.
This means subtracting 42 from the result we got in the previous step, which is 8.
So, 8 - 42 equals -34.
Finally, multiply -34 by 4.
Multiplying -34 by 4 gives you -136.
do some fancy stuff and the result is 64
