(6/2)(1+3) is as simple as 1+2x3 > 6÷2(1+2) = ? is a confusing expression.

Now obsess about > something else. BULL SHIT you know not of what you speak. When you solve what is inside of the parenthesis. They are automatically removed from the expression. 6÷2(1+2) = ? 6÷2(3) = ? so this (3) does not exist anymore it turns into 6÷2 x 3 = you idiot.
