NMAI069 (Mathematical skills) - more of the same from last week, as in more propositional logic, what was interesting is that using just negation and the basic ones we defined every possible logic binary operator that could exist


NDMI002 (Discrete mathematics) [lecture] - partition of a set and proof that a if R is an equivalence to a set X, then partitions of R form a partition of X, definition of a partially ordered set and hasse diagrams


NDMI002 (Discrete mathematics) [tutorial] - we finished the proofs that we didn't have enough time for last week and then went onto relations, meaning we had some defined relations and were tasked with finding which properties they have

NMAI069 (Mathematical skills) - we did propositional logic, nothing that i didn't already know


NDMI002 (Discrete mathematics) [lecture] - binary relations, their compositions, how they all relate to functions and composite functions. then we did properties of functions (injective, surjective and bijective) if they are the same size and finite then being injective proves it's surjective and vice versa. properties of binary relations, which are reflexive, symmetrical, anti-symmetrical and transitive


NDMI002 (Discrete mathematics) [tutorial] - we went over types of proofs (direct, indirect, by contradiction and by induction) and then had exercises where we had to prove various statements using those methods
