It’s powerful to still know how to use cross multiplication (here calculating dimensions for a video conversion). Thanks to my math teachers at Bedford Elementary School, Sudbrook Middle School, and Milford Mill High for showing me the power of math… even wacky Bloom Friedman, my 10th grade chemistry teacher, who insisted we learn how to use a slide rule (sorry Blooma, I did forget that).
