This is like a combination of the Voyager message and the math/logic primer from Contact. It's fairly easy to eyeball what is going on: mathematical and geometric equivalents are laid out while introducing new symbols which are deduced based on the mathematical properties, such as the use of a symbol representing pi in combination with the circumference and area of a circle on page 5.
