Any way to parse a math equation from a variable?
Search for "C++ math parser", e.g. muparser or look at the list in The Great C++ Mathematical Expression Parser Benchmark. Or if you want to do it on your own: A C++ Expression Parser Tutorial.

If you have 4+3*2, is there an algorithm to calculate this in one pass? Or do you need to convert to RPN/postfix, then use another algorithm to calculate?
It can be done in one pass. I implemented a pratt parser for this kind of expressions: https://github.com/foolnotion/pratt-parser-calculator
