CORRECTIONS *Propositions vs predicates: So that I didn’t overwhelm the viewer I stuck to just using “proposition” throughout. I know this isn’t strictly correct as many of the statements involving variables are actually prediates. **For some reason when recording I had it in my head that ‘n’ was a British thing when it is widely used throughout the Anglosphere and beyond. ***Slip of the tongue that kind of undermines my point — the converse of Legrange’s Theorem would be “H is a subset with cardiality dividing |G| ⇒ H is a subgroup of G." ****Another slip of the tongue that undermines the point — we are showing that whenever x is NOT zero, it has a reciprocal y=1/x.
