first-order.adjective
most.fundamental; primary; denoting.mathematical.equations involving only the first power of the independent.variable or only the first derivative of a function
first-order logic.adjective
first-order logic is also called predicate calculus; the language describing the truth of mathematical formulas, which describe properties of terms and have a truth value, such as, and for example, the following are atomic formulas:

   If F1, F2 and F3 are formulas and v is a variable then the
   following are compound formulas:

   F1 ^ F2 conjunction - true if both F1 and F2 are true,

   F1 V F2 disjunction - true if either or both are true,

   F1 => F2 implication - true if F1 is false or F2 is
   true, F1 is the antecedent, F2 is the consequent (sometimes
   written with a thin arrow),

   F1 <= F2 true if F1 is true or F2 is false,

   F1 == F2 true if F1 and F2 are both true or both false
   (normally written with a three line equivalence symbol)

   ~F1 negation - true if f1 is false (normally written as a dash '-'
   with a shorter vertical line hanging from its right hand end)

   For all v . F universal quantification - true if F is true for all
    values of v (normally written with an inverted A).

   Exists v . F existential quantification - true if there exists some
   value of v for which F is true. (Normally written with a 
   reversed E).

   The 'order' of a logic specifies what entities 'For all' and
   'Exists' may quantify over. First-order logic can only
   quantify over sets of atomic propositions, e.g. for all
    p . p => p), example. 

Second-order logic can quantify over functions on propositions; Higher-order logic can quantify over any type of entity; the sets over which quantifiers operate are usually implicit but can be deduced from well-formed constraints
