When creating softwares, many times you need it to perform calculations ot its own.
Not only calculator programs should perform calculations.
The majority of programs do perform calculations.

For example, imagine trying to code a the Mario game.
Every time, the user gets a coin you have to add a coin
to a variable that stores the amount of coins the user have until know.
If you are taking track of the records of points, you may need to
compare the current points to the previous points the user got.

It is just an example. But you get the point.
Programs need a way to perform calculations.
