a calculator aaaaaaaaaaa nmust fill this out to 50 characters aaaaaaaaaaaaaaakkkakakakaaaa
There were some funky bits with your script I noticed. Your numbers were saved as strings, not integers, so none of the functions worked. Addition almost worked, but it just appended the two numbers together.
I changed it so it explicitly defined each number as integers, and it works like a charm. I also changed "Chose" to "Choose", and fixed a few formatting things (that I personally preferred)
