Enter a math problem. Instead of putting negative numbers, please put instead (0-x), in parenthisis
This uses the Shunting Yard Algorithm and postfix notation to solve any problem, even with parenthesis, with just one script to actually solve it! And, you don't need to use spaces. Although, I haven't added exponents to this one YET. I will, though! It displays what you entered (blue), the problem in postfix under it, and the answer under the equal sign. Credit to @Zro716 for the suggestion on this. I learned how to solve problems using this on Wikipedia. Try 4*(3+(7-4))
