Sometimes you don’t want to solve problems in the abstract, you just want to know what a ten year million dollar loan is worth at eight percent interest or something natural language like that. I type it into Google and it usually unrolls it and calculates it pretty well or finds a site for the problem. I hope this calculator has a good natural language vocabulary.
ya google is great with understanding natural language and providing either direct result or pointing to appropriate website.
My goal is to improve Hissab's natural language capabilities as much as I can.
Also, regarding the example you mentioned about calculating interest, I will be adding those features in the form of a function like simple interest(principle=1M, rate=8%, duration=10 years) etc. Its not natural language, but once you learn, and you do this a lot, hissab will come handy.
