Both books are mirror images of each other…
…both have full number lines, neither are price clipped and on a scale of 1-10 I’d give them both an easy 7.5.
You can buy one or you can buy both…
…it’s a discount if you buy both…buy 2 keep 1 sell the other…there you go.
The books are $30 EACH or two for $50-bucks…buy one to keep and sell the other one.
