Books Puzzle Escape

Started slow as I clicked around expecting more things to be clickable. I eventually figured out where the promised puzzles were. Once I found them I had seen most of the room so they weren't too difficult.

heidavey: 3÷1 = 3, 4÷1 = 4. Not a mistake.

There's a mistake in the green puzzle. The bottom right section should say "4x" not "4:" and the bottom left should say "3x" and not "3:"
