How to start C++ programming project on mathematical equation?

my lecturer ask us to do some programming mini project . I need some help on how to start this project ,because this is my first time use c++ .if you have any manual on how to do the mathematical problem,can you share to me??

You can choose any algorithm you had in your data structures class and understand it properly and implement it in different way and you can implement it by adding animation to it. You can choose greedy algorithms and searching and sorting algorithms and they will use mathematical equations. 

You can do ATM simulation, Banking management, Blood bank(calculating sugar level) all these topics use mathematics. 

Mathematical project is actually weird statement, I guess. The project depends on certain use case and in that you need to apply mathematical equation. So please specify which type of application you are looking for and accordingly the equation will fit. 

Some applications which I have created was Banking console application in which there were features like withdrawal,  Bank Balance Display, Deposit, Transaction per day, etc. So here some mathematical equations were used. I hope it clears your doubt and please be specific in questions.

Can you post your mathematical equation so that we will know what you are talking about so that we should be in a position to answer you? 

Mathematical equation is very generic term. Please give the equation.
