Click the numbers and then the operation.. It DOES NOT support numbers with more than 2 digits (I will fix this in the near future).
Yes, yes I know Its really bad but I'm not a great scratcher and I find really hard to understand lists and variables so I just did this to practise. THAT IS ALL. ------------------------------------------------------------------------------------------- I know the script is probably over complicated but I tried. The 'm' list does the operations. The 'n' list makes the numbers show. 'n1' is the first input and 'n2' is the second.
