Bizzare

Thought it was bad design at first then I realized this is a poorly conceived CS project that cant even do the basics and the creator eventually just said f it im gonna go get high. Lets say you want to do 2+1 then hit enter. The output should be 3 and if you want to continue and multiply this normally you just hit "x" and it would say "ans x". It doesnt do this. Also theres the "your mum" output on stat functions. Entering the URL for the website fails but when I google it then link through there it comes up but the page is pretty sparse.
