The expression 9 + 9 ÷ 9 − 9 must be solved using the correct order of operations.
Complete the division first:
9 ÷ 9 = 1
The equation now becomes:
9 + 1 − 9
Calculate addition and subtraction from left to right:
9 + 1 − 9 = 1
The correct answer is 1.
Many people get a different result because they calculate the expression from left to right without completing the division first.
