This is a very simple math solver. Simply enter the expression you want to get the value of, and the program will tell you the answer. Note that this only evaluates/simplifies expressions which don't include (algebra) variables. I'd love to make it possible to use variables, but without first class lists (ala Snap!), it'd be a pain, so I kept it simple and limited to plain old decimal numbers. It supports: - Integers and decimals (positive and negative). - Decimal addition and subtraction (using builtin +, - blocks). - Decimal division and multiplication (using builtin *, / blocks). - Exponentiation (positive and negative, but not fractional). - Parentheses/brackets (even nested). - Order of operation, for all operators. Error catching would be nice (tm), but the attempt to add it turned Very Futile; I haven't figured out a good system for throw/catch/tracebacks in Scratch yet! I'm pretty sure it can't get into any infinite loops, though, and it's otherwise fairly fast. I guess I can't check if it gets into any never-ending loops, though. :)
