As opposed to the study of calculus or real numbers which deal with continuous variables, Discrete Structures deals with graphs and statements in logic which can be enumerated through the implementation of integers. Study Hard! Until computers came along, most math students took a calculus sequence. Usually, 500GB hard disks are common in modern computers. For example, youll be hard-pressed to nd a mathematical paper that goes through the trouble of justifying the equation a 2b = (ab)(a+b). This is usually the first mathematics course for computer science students; it helps them to start thinking about problems in a way computers can solve. Of course, the same is true - though, IMHO, to a lesser extent - of calculus. A tautology is a compound proposition whose truth table is all true, whereas a contradiction is Discrete objects can often be enumerated by integers. A Computer Science portal for geeks.
