How to read this

Swapping the order does not change the answer, so 7×8 and 8×7 are one page.
Moving one step along adds that table — the sevens grow by seven each time.
Division undoes multiplication: 56 ÷ 7 = 8 means 7 × 8 = 56.
Some products come from more than one pair — 24 is 3×8 and also 4×6.
