About the course

In this project, you will create a four function calculator in Scratch.  Your calculator will be able to add, subtract, multiply, and divide.  You will learn about operands and operators, and you will work hard to ensure your calculator is able to handle anything the user can throw at it!  For example, what should happen if the user presses an operator button without first entering a number?  Error checking and error prevention are important parts of software development, and programmers often spend as much (or more!) time on those as they do on the core functionality in their applications.
