actually if you distirbuted out the 3 from (9+3) it would be as follows:
48/2*3(3+1)
you cant just multiply 2*3 and ignore the order of operations which just goes to show you cant just distribute whenever you want and move stuff around. Everyone is so used to there being a + sign in front of where the 2 is and distribute first.
I’ll also add i think the answer should be 2, based on my belief that there should be a rule that implied multiplication should come before explicit. But there isn’t a rule and I don’t like how you are going on about how your Russian education far exceeded your american one, and how you refuse to see where you may be wrong in some way.
