SUMMARY

The discussion focuses on matrix operations, specifically solving for A+B, AB, BA, AC, and CA. Participants confirm the correctness of their matrix calculations while addressing potential issues with matrices of unequal dimensions, such as A having 3 rows and B having 2 rows. The use of macros in LaTeX for simplifying matrix representation is also highlighted. Overall, the conversation emphasizes the importance of understanding matrix dimensions in operations.

ok I think I did these are ok but knowing how tedious it is might be some typos
also does this work if you have different unequal rows for example if A had 3 rows and B had 2 rows

the pic is just a snip from my overleaf doc. I used macros to avoid long latex code in the bmatrix
