Just got through the 2021 book "Math without Numbers" by Milo Beckman, which I picked up just because I found the title intriguing. Turns out it isn't even first book with that name. It got some bits about topology, diagrams, cellular automata. It's simple enough that kids can read it. When it comes to practical applications of math, he mentions neoclassical economics of all things, quote "…in some cases, this supply–demand model actually makes pretty decent predictions". Just a very small part of the book, but eeh.
