Enter a math problem! This is much better than the previous version. It now has full support for negative numbers, and can multiply by putting a number before a parenthesis. You could enter something like 9(2*-3). Inside, it also has a debug log that keeps track of everything as the algorithm converts it, if you wanted to see the process of it converting your problem. And, it has error detection now, so instead of freezing up the project, it tells you the error. If you put 3*(4+3)) it would say "mismatched parenthesis."
UPDATE- It now does modulus and has argument separators. mod(5,3) would be the same as ((5) mod (3)) with Scratch blocks. You can also put math operations in the arguments. mod(2+3,3) is the same as mod(5,3) UPDATE-Now you can enter constants pi and e. Make sure you still use the multiplication symbol (*) when multiplying! This uses the Shunting-Yard algorithm to convert an infix notation problem (like 4+3) to postfix notation. 4 + 3 would become 4 3 + For more information about the shunting yard algorithm, go to http://en.wikipedia.org/wiki/shunting-yard_algorithm For info on postfix notation, go to http://en.wikipedia.org/wiki/Reverse_Polish_notation
