### The No Keyboard Challenge

Here's my little contribution, it's very similar to example project pong:

Hm, this got a lot harder in Scratch 3 due to less reporters coming pre-filled and the “10” trick not working

We do, however, get “my variable”

You're going about this the wrong way by deriving 0, 1, 2, 3, etc. individually. You need to use induction to get all the numbers.

For 0, you can use

`(() + ())`

For 1, you can use

`<not <>>`

Then, you can create any natural number by adding together a bunch of 1's. For example, this is 2:

`(<not <>> + <not <>>)`

To get negative numbers, use

`(() - ())`

To get “rational” numbers (technically declmals) use

`(() / ())`

The formalization here resembles the formalization of the naturals (inductively, {0, 1…}), then the integers (pairs of natural numbers), then the rationals (pairs of integers).

You can import sprites from the default library and use:
`(costume [name v] ::looks) // new in scratch 3.0`
to get almost every single character.

This was actually possible before with backdrop name. Costumes could be dragged into the stage.

`(letter (<not <>> + <not <>>) of (backdrop name))`

`when signature read:: events hatsay [Not much here…] for (2) secs`

This is a bump to say that I've finally updated the original post for Scratch 3.0!
