In the early 1970's, I saw the & appear in some of our older alphabet books. The absolutist child in me tried to work out if that bit of archaic data was authoritative or not.
Those books were likely printed in the 1950s.
- GloomyBoots 3y agoA few years ago I was idly thumbing through old books at a used store. Looking over a remedial arithmetic book, I was surprised to find that they referred to zero as “the cipher”. Exponentiation and the process of finding a square root were “involution” and “evolution”, respectively. My math education was pretty ad-hoc (complicated story), so maybe these are better known than I realize, but I’ve never heard them. I ended up grabbing the book just for the vocabulary. These examples are just the ones that jumped out most in the first couple of pages.
