Improve notebook 1

[moreymat]

• function definition :

  • make indentation clearer (move up from where it was?)
  • make parameter calling (no need to re-state the /) clearer
  • return vs print : they just seem to be the same in the notebook, find a way to clarify and explain better

• while vs for : explain better ! we can use both for the same thing, but...
  or maybe skip while altogether ?

• notebook quirks : only the latest result of the computation is printed

• add a link to wikipedia on integer division
