Stupid question :D

[Guest offline]

when you enter
6/(2(2+1)) in any calculator than the answer will be 1.
and
6/2(2+1) in any calculator than the answer will be 9.
It is not the stupid question by any way at all.

PEMDAS Parentheses, Exponent, Multiply, Divide, Add, Subtract
6/2(1+2) First Parentheses = 6/2(3)
6/2(3) No exponents so multiply = 6/6
6/6 Divide =1
1 is the answer

6/2(1+2)....

As written, it is ambiguous due to the improper use of parentheses. It could be interpreted as either (6/2)*(1+2) = 9 or 6/[2*(1+2)] = 1. As written, a calculator is likely to interpret it as (6/2)*(1+2), since the lack of parentheses generally indicates only the immediate following term is assumed to be in the denominator. This isn't a PEMDAS issue (i.e., order of operations) issue so much as a poor notation issue.

first you have to make division, just after that multiplication. that why it is 9

You should try and use PEMDAS ( parenthesis , exponents, multiplication , division , addition , and subtraction!
