Some expect reverse Polish instructions, and some expect straightforward instructions resembling the way you would actually write an arithmetic problem on paper. If you bought the calculator new, doesn't it have an owner's manual?
Why would you think that anyone on this website could answer such a vague question, where you didn't even say what make/model the calculator is?
Dude you can get help from the user manual.the calculator can be used to solve quadratic,cubic equations and it can it can perform calculus functions to name a little.you should bother yourself to know more about it.it can't be learnt within a day.
