Re: Discrete math

hi Mknb

Welcome to the forum.

I would like to help but I cannot understand this notation.  Where did it come from?

I've search on-line and found 4 sites that list symbols to use and I still cannot find yours.

Have a look here:

https://en.wikipedia.org/wiki/List_of_logic_symbols

and then, please,  re-write the question using these.

Thanks,

Bob
