Enter a math problem. Put spaces in between numbers and symbols, and don't use parenthesis.
Now it can even use exponents! I got the block for it from @DadOfMrLog. This project will solve the problem you enter using the order of operations. You can even enter negatives and exponents, like 3 ^ 4 * -6! Remember, you must put spaces between numbers and symbols. 4+3 won't work, but 4 + 3 will. It can't do parenthesis.
