The equation 7 + 7 ÷ 7 − 7 looks simple, but the division must be completed before the addition and subtraction. Start with 7 ÷ 7, which equals 1.
The expression then becomes 7 + 1 − 7. Work from left to right: 7 + 1 = 8, and 8 − 7 = 1.
The correct answer is 1.
A common mistake is to read the equation strictly from left to right before handling the division. That changes the result. The safest approach is always to complete multiplication and division first, then finish addition and subtraction.
If you got 1 without using a calculator, you followed the standard order of operations correctly.
