…i really think that the thing to question is what the original problem is. Since some calculators have different formats than others, it really is just dependent on the format of the calculator and how you type it in. The black calculator treats everything to the right of the division sign in the entered problem as belonging in the denominator of the fraction 6/((2(1+2)) which does equal 1. The silver calculator treats the entered problem like this (6/2)(1+2) which equals 9. Either way, there isn’t really a sure way to know which is correct without knowing the original problem. The ambiguity resulting from the lack of parentheses is quite depressing. Additionally, you can notice that these are different models, they probably just have different defaults, but you must use more parentheses to get the answer you want!

BIDMAS says 9.

I am dissapointed by the stupidity of people.
“The answer is 9. It’s sad that we have to even use claculators to do this…”
It is not. The first step in that kind of a problem is to open the brackets. It would equate in 6 / [ ( 2 * 1 ) + ( 2 * 2 ) ] = 6 / ( 2 + 4 ) = 6 / 6 = 1
