What You'll Learn

This course gives you the following verified skills and competencies in Teaching & Academics:

How to solve problems in chosen Discrete-Mathematics topics (illustrated with 412 solved problems) and why these methods work, with step-by-step explanations. .
Combinatorics, continuation from DM1: permutations, variations (with and without repetitions), combinations; some problems formulated (but not solved) in DM1. .
More combinatorial topics, including counting multisets (method by sticks and stones) and a generalisation of the Inclusion-exclusion principle (two versions). .
An introduction to some advanced topics: partitions of sets, multinomial coefficients, Stirling numbers, and the Twelvefold-Way group of problems. .
Various types of proofs of binomial identities: direct proofs, using the Binomial Theorem, induction proofs, proofs by telescoping sums, combinatorial proofs. .
A very brief introduction to (discrete) probability, with some typical examples of experiments like tossing a coin, and rolling dice; probability in poker. .
Some basic concepts in Probability: experiment, outcome, sample space, event, favourable event. .
Combining events (union and intersection of events), mutually exclusive events, complementary event. .
Independent and dependent events, conditional probability. .
Random variable and its expected value (just enough for the Secretary problem). .
Basic concept in Number Theory: prime and composite numbers, divisibility, gcd (greatest common divisor) and lcm (least common multiple), quotient, remainder. .
Euclid's algorithm for multiple purpose (finding the gcd and lcm, solving Diophantine equations, and solving linear equations in modular arithmetic [S6], etc). .
The sum-of-all-divisors formula (based on prime factorisation). .
Euler's totient function (number of natural numbers less than n, relatively prime with n). .
Number representation in different positional systems (decimal, binary, etc). .
Modular arithmetic, counting modulo n, an introduction to the rings Z_n. .
Various properties of modular arithmetic; solving simple congruence equations. .
Tests for divisibility (by 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16). .
Fermat's Little Theorem with four proofs (one of which really delightful). .
Euler's Totient Theorem as a generalisation of Fermat's Little Theorem. .
A basic introduction to main algebraic structures (groups, rings, fields, vector spaces) with some nice examples using the theory from S5 and S6. .
Examples of associative and commutative binary operations defined on different sets, also some examples of operations not having these properties. .
The concepts of a subgroup and a cyclic group with some arithmetic and geometric examples. .
The concept of homomorphism and isomorphism with some examples; properties of homomorphisms; isomorphic groups. .
Invertible elements in Z_n; the fields Z_p with addition and multiplication modulo p; the group of units U_n. .
An introduction to (symmetric) groups of permutations and their subgroups; multiplication of permutations. .
Lagrange's Theorem at the end of the course puts together many elements of DM: groups, number theory, equivalence relations, and partitions of sets. .
Direct product of a number of rings Z_n and a natural isomorphism between this ring and Z_N: a preparation for the Chinese Remainder Theorem (planned for DM3). .
Some geometric examples (dihedral groups: isometries of an equilateral triangle and isometries of a square). .
The course contains a bunch of really fun (maths-competition style) problems, mainly in Section 6.

Course Requirements & Prerequisites

The following background knowledge and tools are recommended before starting this course. Students without these prerequisites may still enroll but should expect a steeper learning curve:

Basic high school mathematics (mainly arithmetic)
Discrete Mathematics 1 (or equivalent: logic, sets, functions, relations, proof techniques, basic combinatorics)
You are always welcome with your questions. If something in the lectures is unclear, please, ask. It is best to use QA, so that all the other students can see my additional explanations about the unclear topics. Remember: you are never alone with your doubts, and it is to everybody's advantage if you ask your questions on the forum.

Is the Discrete Mathematics 2 Coupon Worth It?

Expert review by Josh Smith, Lead Course Reviewer at CourseSpeakUpdated Aug 3, 2026

The short answer is yes — provided the Teaching & Academics skills this course teaches actually line up with what you want to build. The regular price for Discrete Mathematics 2 on Udemy is $149.99. The coupon code listed on this page drops that to $9.99 — a saving of $140.00, or 93% off the standard rate. Spread across 66h 30m of on-demand video, that works out to roughly $0.15 per hour of content — less than the cost of a single chapter of most printed teaching & academics textbooks.

A discount is only worth something if the material delivers, and the curriculum here is built around practical outcomes. Hania Uscka-Wehlou walks you through how to solve problems in chosen Discrete-Mathematics topics (illustrated with 412 solved problems) and why these methods work, with step-by-step explanations., combinatorics, continuation from DM1: permutations, variations (with and without repetitions), combinations; some problems formulated (but not solved) in DM1., and more combinatorial topics, including counting multisets (method by sticks and stones) and a generalisation of the Inclusion-exclusion principle (two versions). — concrete skills you can apply, not abstract theory. It has already been taken by 685 students and holds a 4.9-star average from verified reviews, which is a reasonable sign the content holds up in practice.

The bar to entry is low: Basic high school mathematics (mainly arithmetic); Discrete Mathematics 1 (or equivalent: logic, sets, functions, relations, proof techniques, basic combinatorics). That makes it a realistic choice even if Teaching & Academics is unfamiliar territory. In practical terms, expect around 66h 30m of on-demand video to work through at your own pace. The material is presented in English.

Pros

  • Verified 93% price reduction.
  • High learner satisfaction (4.9/5).
  • Trusted by 685 students.
  • Certificate + lifetime access.

Cons

  • !The coupon is time-limited — once it expires, the price tends to revert toward the standard $149.99.
  • !Lifetime access is tied to Udemy staying online; the platform can change its policies.
  • !Budget for the exercises and quizzes too — they add real time on top of the 66h 30m of video.
