The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Exercise - Abstract Contract Calcul

The video tutorial introduces an abstract base contract named 'calculator' with a public function that returns integers. It then guides viewers to create a derived contract called 'test' that inherits from 'calculator' and performs a simple calculation. The exercise involves understanding these concepts and writing the code to solve the problem. The video concludes with encouragement and a preview of the next session where the solution will be discussed.
