This puzzle is a good reminder that the order of operations matters, even when the numbers are simple.
The expression is:
7 + 7 ÷ 7 + 7
Division comes before addition, so start with:
7 ÷ 7 = 1
Now the expression becomes:
7 + 1 + 7
That gives:
15
So the correct answer is 15.
The common mistake is adding from left to right before doing the division. But multiplication and division must be completed before addition and subtraction.
Answer: 15.
