This math puzzle looks simple, but the order of operations matters.
The expression is:
7 + 7 ÷ 1 × 0
Division and multiplication have equal priority, so calculate them from left to right:
7 ÷ 1 = 7
7 × 0 = 0
Now finish the addition:
7 + 0 = 7
The multiplication by zero affects only the second part of the expression.
Answer: 7
