A React application to solve simple math operations. Currently, there are five options available:

• Simplify
• Factor
• Derive
• Integrate
• Find 0's

Newton API —a really micro micro-service for advanced math— is used to get the result.

The result is displayed with KaTeX, using react-katex.

Validity of an expression (whether it is well-formed) is checked with the help of math-expression-evaluator. Since the expressions can be complex equations, it is hard to do a 100% coverage, but it is sufficient for evaluating simple strings. That said, something like abcd+efg is well-formed, but 123++- is not. In that case, an error message informing the user is displayed.
