Sleepy, Sneezy, Grumpy, Doc, Happy, Bashful, Dopey and Snow White met up for lunch.
Everybody shook hands with everybody else once.
How many handshakes took place?
How did you solve the equation?
But first… Problem of the Day!

What is an equation? Give me an example. A mathematical sentence that shows equality.
Equations always contain the “=” symbol. What is an expression? Give me an
example. A pattern for similar problems. Expressions do not
contain the “=” symbol.
What is a variable? Give me an example.
What is a coefficient? Give me an example.
