It’s knowing the order of operations.
Let’s solve the expression carefully.
Step 1: Solve the parentheses
Start with:
8 − 4 = 4
The equation becomes:
7 − 2(4)
Step 2: Multiply
The expression 2(4) means:
2 × 4 = 8
Now we have:
7 − 8
Step 3: Subtract
Finally:
7 − 8 = −1
✅ Correct Answer: −1
So the complete solution is:
7 − 2(8 − 4) = −1
Why Do Some People Get 6?
The confusion usually comes from doing the subtraction too early.
Someone might look at the first part and calculate:
7 − 2 =
