|
Title "Addition World"
|
|
|
|
Introduction
|
|
"
|
|
Welcome to Addition World! In this world we'll learn the `induction` tactic.
|
|
This will enable us to defeat the boss level of this world, namely `x + y = y + x`.
|
|
|
|
The tactics `rw`, `rfl` and `induction` are the only tactics you'll need to
|
|
beat all the levels in Addition World, Multiplication World, and Power World.
|
|
Power World contains the final boss of the game.
|
|
|
|
There are plenty more tactics in this game, but you'll only need to know them if you
|
|
want to explore the game further (for example if you decide to 100%
|
|
the game).
