Storing with variables We'll often want to store the results of mathematical expressions in variables, especially if we want to reuse the results of a calculation later.

What is the difference between computer science and computer programming? Explore the origins of programming languages to understand what it means to program.

Big data sets are so large that our traditional ways of storing and processing them are no longer adequate, presenting challenges to computer scientists and data engineers.

Once we've defined that function, we can call it whenever we'd like, and the computer will execute the statements that are inside the function block (between the curly brackets).
