So it is! Okay--now we can start adding these numbers. Like, what's 1 + 1, according to rule (3)? A. You work on that, and I'll work on 1 + a. B. Okay,Iget ({0+1,0+1},0). AndO+1is ({0+0},0);0+Ois (O, O) = O. Everything fits together, making 1 + 1 = ({I}, O) = a. Just as we thought, a must be 2! A. Congratulations on coming up with the world's longest proof that 1 + 1 is 2. B. Have you ever seen a shorter proof? A. Not really. Look, your calculations help me too. I get 1 + 2 = ({ 2}, 0), a number that isn't created until the fourth day.

Such cases would be ruled out by (T13), but ... A. But we need (T13) to prove (T14), and (T14) to prove (T13). And (T13) to prove (T12). B. We're going around in circles again. 67 A. Ah, but there's a way out, we'll prove them both together! We can prove the combined statement "(T13) and (T14)" by induction on the day-sum of (x, y, z)! B. (glowing) Alice, you're a genius! An absolutely gorgeous, tantalizing genius! A. Not so fast, we've still got work to do. We had better show that x -x =o. (T15) B.

Oh, I doubt if we'll need that; it didn't come up in the calculations. But I suppose it won't hurt to try it, since my math teachers always used to think it was such a great thing. 65 One associative law, coming right up. Can you work out the definition? (x+y)+z A. + y) + z) U ((YL + X) + z) U (Z L + (X + y)), ((XR + y) + z) U ((YR + x) + z) U (ZR + (x + y))) = (( (XL X+(y+Z) = ((XL + (y + Z)) U ((YL + Z) + x) U ((ZL + y) + x), (XR + (y + Z)) U ((YR + Z) + x) U ((ZR + y) + x)). B. You're really good at these hairy formulas.
