Discrete mathematics, sometimes called finite mathematics, is the study of mathematical structures that are fundamentally discrete, in the sense of not supporting or requiring the notion of continuity.
Discrete mathematics has become popular in recent decades because of its applications to computer science.
Concepts and notations from discrete mathematics are useful to study or express objects or problems in computer algorithms and programming languages.

Apportionment may include division of discrete objects, as in the division of seats of a representative government among districts, or may involve division of continuous objects such as dividing a cake among a group of people.
Discrete mathematics problems can be classified in three broad categories, existence problems, counting problems and optimization problems.
When an event can occur in a finite number of discrete outcomes, the probability of an event is the ratio of the number of ways in which the event can occur to the total number of possibilities, assuming that each of them is equally likely.

Theorem 1: $f(n)=2n-4$ for $n>4$." - Gerald Berman; The Gossip problem, Discrete Mathematics 4 (1973) 91 (Corrigendum p397) MR 46 # 7037 The author gives a simple (but, as pointed out in the corrigendum, incomplete) solution of the gossip problem of B. Baker and R. Shostack [Discrete Math.
MR 92a:05074 The gossip problem is to determine the minimum number of telephone calls which must be made among $n$ persons so that each person can obtain the information known by all the other persons, assuming that when a call is made, the two persons share all the information available to them.
Thus if the edge labels correspond to the time of the telephone calls, finding the minimum number of edges in a label-connected graph on $n$ vertices is equivalent to solving the gossip problem.

Either we consider intersection graphs of finite sets, and call the models discrete.
For instance, by only recognizing intersections of a certain size we arrive at t-intersection---for discrete models, or tolerance intersection--- for geometric models.
If we know for each pair of sets in a discrete model the size of the intersection, we get intersection multigraphs.

 05: Combinatorics
Combinatorics (Section 05) is one of the larger sections of the Math Reviews database, but this is largely because of the size of Graph Theory (05C), one of the largest of the three-digit areas.
The subject is also frequently taught to quite new students, hence there are a number of textbooks covering combinatorics together with matrices, elementary logic, or topics of "discrete mathematics".
Sometimes the easiest way to get information on a counting problem is to compute a few small values of a function, then look for a match at the sequence server; if you find a hit, you can sometimes get citations to the literature.
