The expression 3 + 3 × 3 ÷ 3 − 3 must be solved using the correct order of operations.
Multiplication and division have equal priority, so calculate them from left to right:
3 × 3 = 9
9 ÷ 3 = 3
The equation now becomes:
3 + 3 − 3
Calculate the remaining operations from left to right:
3 + 3 = 6
6 − 3 = 3
The correct answer is 3.
