Summary

Now that you have read this chapter, you hopefully have a calculator program that you can run! This program is more interactive and can do more things than your first program, so you should share this program with your family and friends to show them how you have improved your skills.

In the next chapter, we will learn about how decisions are made, and we will improve our calculator program by teaching it how to let a user choose which operation to perform as well as how many operands (numbers) to enter. We are going to get into things that are a bit more complicated, but we will go through them step by step so that you can understand each piece of what we are doing.
