2(9+3) is one term by defintion



Then order of ops

48/ 2(9+3) You must solve the () first

48/(18+6)

48/24 = 2

Bzzzt! Thanks for playing. Read below.

doing proper distributive, would be
48/2(9+3) = 48/2*9 + 48/2*3


apply distributive rule,
a/b(c+d) = a/b*c + a/b*d
Ding, ding, ding!!!

Thank you, I was about to post that myself.

Part of the problem taken out of context can be dangerous.

You could rewrite the portion of the equation in question as

(48/2)(9+3) which gives 9x24+3x24 which is 12x24 which is 288

same goes for the problem that you suggested.

(16/2)(8-3(4-2))+1
8(8-3(2))+1
8(8-6)+1
8(2)+1
17
