Question

What is 6 devided by 3 parenthesis 2 plus 1

Answer 1

If you mean (6/2)2+ 1 you would get 5

Answer 2

6/3(2+1)

Following the PEMDAS, in this problem you would start off with what's inside the parentheses.
6/3(2+1)
6/3 (3)
And then, you do the division (since if I'm correct, left to right..), 6/3=2. Finally you would multiply the 2*3=6.
