Variables are important in Ruby. They're a way of giving information a reference that we can use later. We give a value to a variable with an = sign.

See that? Just as I can only point you in one direction at a time, variables can only point to a single value at a time.

Psst: Ruby will reassign the variable to whatever value we give it, so we need to be careful with those variable names.

Not quite! Didn't we say we want to use the = sign?
