Algebra Beneath Me

Sammy was studying Algebra with Daddy, how to combine like terms.

Daddy: So can you answer this?  (2xy + x + 5xy = 20)

Sammy: (Confused) There’s so many letters! How can I find out what x and y is?

Daddy: We’re not looking for the values, they don’t have any values.

Sammy: Oh. (Glaring at the letters) You are worthless to me!
