First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables, so that rather than propositions such as "Socrates is a man", one can have expressions in the form "there exists x such that x is Socrates and x is a man", where "there exists" is a quantifier, ...

What is 1st order logic vs 2nd order?
First-order logic quantifies only variables that range over individuals; second-order logic, also quantifies over sets; third-order logic also quantifies over sets of sets, and so on.
Why is first-order logic useful?
First-order logic allows us to build complex expressions out of the basic ones. Starting with the variables and constants, we can use the function symbols to build up compound expressions like these: x+y+z. (x+1)×y×y.
