I love it. It's literally just a barrage of math, separated into little bite-sized chunks.
Modern textbooks can have a so much fluff with all the flashy pictures and icons and the text on the page being brightly colored or having bubbles drawn around it to be more "engaging" etc.
I found it super annoying as a kid, wish I had something like this.
This is a book of mathematical results without derivation. Most textbooks that people learn from include proofs.
It's easy to understand how a person with no formal mathematics training could read this book, try to figure out why these results are true, and in doing so, gain an intuitive sense about numbers and operations on them without developing the rigor to be able to state proofs for why anything should be true.
