I have just started learning introductory discrete math and I am kind of confused. I can't see the difference between compound statements and statement forms. To me, they look the same according two these 2 definitions:
A statement represented by a some combination of statement variables and connectives is called a compound statement.
Statement form or propositional form is an expression made up of statement variables such as p, q, r and logical connectives that becomes a statement when actual statements are substituted for the component statement variables.
Are they the same thing ? What am I missing here?
