Ace MATH 223
University of British Columbia
MATH 223 is UBC's more theoretical linear algebra course, covering vectors, matrices, linear transformations, eigenvalues, orthogonality, and abstract vector spaces — with actual proofs and deeper mathematical reasoning. It's typically taken by math majors, honors students, or anyone who wants a more rigorous foundation.
Credit-excluded with MATH 152 (for engineers) and MATH 221 (the lighter science version), so you can only take one of these three. If you're seeing Reddit threads asking "152 vs 221 vs 223?" — the answer is: 152 for engineering applications, 221 for science without heavy proofs, and 223 if you want the real linear algebra experience or plan to take upper-level math courses.
You've landed on a page designed to give you everything you need to pass your MATH 223 final.
