STEP 4: Let's start by setting up the functions for our math machine program.

• Click LOGIC, then and drop Define Function at the top of your program.
• Do NOT delete pass!
• Repeat these steps three more times so that you have 4 functions, each with a pass line inside.

pass is a placeholder that does nothing! It lets us define empty functions without causing a syntax error.
