After so many years of using linear algebra, until today I finally understand the meaning of matrix multiplication. matrix*vector is linear combination of the columns of the matrix, and vector*matrix is linear combination of the row of the matrix. Then from this standpoint, the meaning of permutation matrix becomes so obvious. Thank you Prof. Strang.

"Informally we've got by columns by rows by each entry at a time". Such an eye opener.

[@ekdud2772]

there's something about his lectures that make it so easy for me to concentrate and follow along. I think it's because he thinks out loud; verbalizing the literal thought processes he runs through to compute this stuff, like he himself is learning for the first time and trying to understand what's going on. even though he's on a higher level than all of us mathematically, he still retains such a clear understanding of the basics.
