Question
Let R represents color red, O represents color orange, and Y represents color yellow.
In the axiomatic structure, the undefined terms are R, O and Y.
Likewise, x is defined as any strings of O's and Y's.
There are four axioms:
31. – 35.
1. If a string of letters ends in O, you may add Y at the end.
2. If you have Rx, then you may add x to get Rxx.
3. If 3 O's occur, that is O0O, then you may substitute Y in the place.
4. If YY occurs, you drop it.
Using a paragraph proof, given that ROOOYYO0000, prove ROOY.
