Quick Math Course (Math Hacks, Cochrane 2018)

Rich Cochrane. Math Hacks (2018) 100 math concepts and theorems present in two-page spreads showing an overview (explanation in math terms, often some history), a shortcut (some details to clarify ), and a hack (brief summary, sometimes with a pointer to related math). Nicely done graphics, good history, well done examples, and a few annoying typos.
