You have to implement a parser to parse the expressions allowed, and then an evaluator which evaluates the expressions to generate a result. It's not trivial in any language. – Some programmer dude Dec 16 '19 at 12:38

And as mentioned this is not a trivial subject or suitable for beginners. You need to know your chosen language well, and you need to know many algorithms and data structures well too. – Some programmer dude Dec 16 '19 at 13:09

Try this:
var myNum= "(20+30+20)/45*100"
parseInt(myNum.replace(/\D/g,''));
