Summary
I began by teaching you about operators and operands in general. I also taught you about expressions and statements. I gave a very briefintroduction to type.
I presented and explained a sample Scratch program that illustrates how to use arithmetic operators in Scratch.
Finally, I provided the specifications for a student-programming project for you to write in order to demonstrate your understanding of what you learned fromthe first program.

What's next?
This module concentrated on arithmetic operators. The next few modules will deal with relational and logical operators as well as selection and loops.
