2) The convention for order if operations is multiplication & division are at equivalent hierarchical levels & so are calculated in order left-to-right, so 6 divided by 2 = 3.
3) A number preceding parentheses without an operation symbol is multiplication. So then it’s just 3 x 3 = 9.
The correct answer is 9. QED.
