What you'll learn From the course description
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.

Coupon & redemption FAQ
Is the Udemy coupon for "Discrete Mathematics 2" still valid? +
The coupon was last checked on August 3, 2026 and was working at that time. CoursesWyn re-checks coupons on a regular schedule, so the status on this page reflects our latest check — coupons can expire or run out of redemptions between checks.
How do I claim the Udemy discount or free coupon code for "Discrete Mathematics 2"? +
Click "Claim Coupon" on this page. The Udemy coupon is applied automatically at checkout, so you don't need to type the discount code manually. If the price doesn't drop, the coupon has expired — the price on the checkout page is the source of truth.
Can I download the certificate after completing this course? +
Yes. Enrolling gives you lifetime access to the course videos, and once you finish you can download a completion certificate directly from Udemy. No coupon page like this one is needed after enrollment.
What happens if this Udemy coupon code is expired when I click it? +
You'll see the full course price on Udemy instead of the discounted price. The price on Udemy's checkout page is always the final authority — refresh this page later to see if a fresh coupon has been recorded.
Does CoursesWyn review or grade the course content? +
No. CoursesWyn records coupon validity, price, and public catalog data only. Rating and review counts shown are Udemy's own published figures, not CoursesWyn's opinion.
