Another word that I can’t say: distributivity.
I actually felt good this time, even though I improvised a bit with showing the relationship between a linear system of equations and its homogeneous counterpart. That became too abstract, so a student asked for an example, which is good since I never thought about it. That took some time, though, but it was good.
I took a lot of time and finished preparing the first midterm. It’s probably too long…even though I cut it down a bit.
