NTVY014 (Physical education I) [swimming] - practised more of backstroke and breaststroke (i can finally sync up the breathing right!!) started on front crawl, it is difficult..

NMAI057 (Linear algebra 1) [lecture] - mostly stuff i did not comprehend, focusing on subspaces and linear span, will have to look into it more when i have time, also linear independence which i somewhat understand!

NMAI057 (Linear algebra 1) [tutorial] - didn't do well on last week's quiz, but i think i demolished today's, after we found an inverse of a matrix within a skew field and some other things with skew fields, little bit on vector spaces

NTVY014 (Physical education I) [swimming] - we finally did proper backstroke, arms and legs and everything! and also breaststroke legs but on stomach, still no breaststroke arms though

NMAI057 (Linear algebra 1) [lecture] - attributes of inverse matrices, attributes of regular matrices, and matrix equations, after we started with groups and its axioms: association, neutral term and inverses.. also abelian groups

NMAI057 (Linear algebra 1) [tutorial] - quiz, i thought my solution was good but i must have made a small computational error because when plugging in my answer on the first row it was off by two and i didn't find the error, after the quiz we did proofs of matrix arithmetic statements, then matrix multiplication.. one is clearly easier, but either can appear on next week's quiz
