We can just give the function numbers directly.
You have 2 cheeses!
You have 3 boxes of crackers!
Man that's enough for a party
Get a blanket.

Ok,we can use variables from our script
You have 10 cheeses!
You have 50 boxes of crackers!
Man that's enough for a party
Get a blanket.

We can even do math inside too
You have 5 cheeses!
You have 14 boxes of crackers!
Man that's enough for a party
Get a blanket.

And we can combine the two,variables and math
You have 15 cheeses!
You have 62 boxes of crackers!
Man that's enough for a party
Get a blanket.
