RE
Nope you got it wrong. You didn’t look carefully and mixed up zeros and O’s (which was my point I’m just surprised the point came across so well )
Question was
40 + 2O – 0 x O = ?
where O = 2
Translates to
40 + 2(2) – 0 x 2 = ?
40 + 4 – 0 =44
But the truth is its not your fault it is hard to tell zero’s and O’s apart, and (near?) impossible to do so in writing. So the fault is not in you but in the unclear question.
Similarly 2x/3y-1 if x=9 and y=2 ?
Is unclear:
is it 2x/(3y-1) ? ( = 3.6)
is it (2x/3y) -1 ? (= 2)
(2x/3)y-1 (=11)
2(x/3)(y-1) (= 6)
among others
Granted some of these make morse sense than others but more than one could have been meant. when typed out it is impossible to convey in a way that is clear to all what the numerator/dividend is and what the denominator/divisor .
So none of these answers (3.6, 2, 11, 6) are incorrect per se*. The question is unclear much like 40 + 2O – 0 x O = ? (especially when handwritten) is unclear
*Ok some are silly, but definitely more than one especially the first 2 can be equally valid
