Hi Rudi,

A number is not a missing operator.

I think it must be some new operator, that is rarely used.  One I have not heard of. 

 

Here is another possibility but still more than one operator has been introduced.

 

\(\lfloor 3*4\div 5 \rfloor=2\)

Hi Melody,

the questioner should have asked for "alphanumeric characters".

I googled it, and apparently, there's an operator called used in coding that would work. It's called operator \(\text{%}\), and it finds the remainder when division is performed. 

 

It would work here, because \(3 \times 4 = 12\), and the remainder when 12 is divided by 5 is 2.


Thus, the missing operator is \(\color{brown}\boxed{\text{%}}\)

Thanks Builderboi, you would think they could have found a symbol that didn't already have another meantng....

I thought there must be some obscure symbol, thanks for finding it.
