If




  • "A" denotes "divided by"

  • "B" denotes "added to"

  • "X" denotes "subtracted from"

  • "R" denotes "multiplied by"


then
$$18R12A4X8B6;=;text{?}$$



$left(Aright)50 quadleft(Bright)102 quad left(Cright)45 quad left(Dright)32$




My Approach $Longrightarrow$ I tried it in two ways



First approach:
$$18timesleft[left(8+6right)-left(12div4right)right]=198$$



Second approach: $$18times12div4-8+6=40$$

    For example 6X4 would be 4-6 not 6-4, since x is "subtracted from".

    What were your instructions? Were you expected to do this from left to right? If not what were the rules. The answer can be anything you want depending on what rules you were given.

    Okay I'd do it, with coffemaths obeservation, as $18R12 = 18*12 = 216$. $216A4 = 216div 4 = 54$. And $54X8=8 -54 = -46$. And $-46B6 = -46+6 = -40$. I don't like to ever call a question a stupid question but for this I'll make an exception.
