Guess What??
I don't even know what to say again.
..
Which of these two calculators got the correct answer??

The way at which you type is the way answer is derived, according to the question
6/2(2+1) it is indirectly 6/[2(2+1)]
So if you type on a phone or a normal modulus calculator,it solve it like this
6/2(2+1)
6/2=3
2+1=3
So 3*3=9
But if you type this into a third party calculator it is solve like this
6/2(2+1)
6/2(3) ...2*3=6
6/6=1
To stop the argument,try to press it in d calculator the indirect way 6/[2(2+1)]
