Discrete Mathematics 3

Our verdict: worth it — as long as the Teaching & Academics skills on the syllabus match what you actually want to learn. The regular price for Discrete Mathematics 3 on Udemy is $149.99. With the coupon code on this page, that falls to $9.99 — a saving of $140.00, or 93% off the standard rate Spread across 53h 30m of on-demand video, that works out to roughly $0.19 per hour of content — cheaper than a single chapter of most printed Teaching & Academics textbooks.

A cheap price means nothing if the material is thin — here the syllabus is organized around usable outcomes. Hania Uscka-Wehlou walks you through how to solve problems in chosen Discrete-Mathematics topics (illustrated with 320 solved problems) and why these methods work, with step-by-step explanations, the concept of number sequences: how we can define them (in various way: explicitly, recursively, verbally, ...) and depict them (as functions from N to R), and a general introduction to sequences, with illustrations, guessing their closed formulas based on various descriptions and proving closed formulas by induction — skills meant to be used, not just watched. It has already been taken by 389 students and holds a 5.0-star average from verified reviews, which suggests the content holds up once learners actually apply it.

Check the prerequisites before you commit: Basic high school mathematics (mainly arithmetic); Discrete Mathematics 1 (or equivalent: logic, sets, functions, relations, proof techniques, basic combinatorics). Best suited to learners who already have footing in Teaching & Academics. Plan for roughly 53h 30m of on-demand video at your own pace. Lessons are delivered in English.
