An expression evaluates to a value and it can be any combination of variables literals and operators. So the order of evaluation is. The parser is a recursive descent parser so internally uses separate parse methods for each level of operator precedence in its grammarI kept it short so its easy to modify but here are some ideas you might want to expand it with.
So the order of evaluation is.
Thus we evaluate a temporary value 12 and now the value is 14. The operators of an expression indicate which operations to apply to the operands.
