About this course

In this course, we will dive into discrete math, the math of computer science! Broadly speaking, discrete math is math that uses discrete numbers, or integers, meaning there are no fractions or decimals involved. In this course, you’ll learn about proofs, binary, sets, sequences, induction, recurrence relations, and more! We’ll also dive deeper into topics you’ve seen previously, like recursion.

Frequently asked questions about Discrete Math

  • You can think of discrete math as math with numbers or objects that are separated from each other. Imagine a line with one-inch tick marks spaced evenly apart — those tick marks would be “discrete.” Similarly, discrete math uses counting numbers (e.g., 1, 2, 3, 4…) because they’re all kept separate from each other.
