When using the distributive property it applies to the 6/2, not just the 2.

It should actually be:
6/2(1+2)
3(1+2) (simplified)
3+6 (distributive property applied)
9 (answer)

When using the distributive property, the "parenthesis first" rule doesn't apply. One of the points of the distributive property is that there is generally something preventing you from doing the parenthesis's first (in more complex problems), and as such, is a "work around" to the "parenthesis first" rule. Hence why you simplify the outside, then apply the property.
