• Learn Python 3

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.

## Reviews from learners

• The progress I have made since starting to use codecademy is immense! I can study for short periods or long periods at my own convenience - mostly late in the evenings.
Chris
• I felt like I learned months in a week. I love how Codecademy uses learning by practice and gives great challenges to help the learner to understand a new concept and subject.
Rodrigo
• Brilliant learning experience. Very interactive. Literally a game changer if you're learning on your own.

## Our learners work at

• 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.
