234 prompts pulled from notebooks 01 to 07, answers at the back

Work in pen. A prompt you can only half answer is the whole point of the exercise: mark it, and go back to the section it names. Generated from every other notebook, so it stays in step with them.

How to read it

Read with a pen. Every notebook opens with a question to answer before you start and asks you to redo the answer at the end, and the margin in the Print edition exists so you have somewhere to be wrong first. The Tablet edition is 16:9 with vector text, so note apps draw on it rather than treating it as a photograph.
