*whats the sum of two and two*

well, 2 plus 2 equals 4, so sum of 4 could be 1, or 2, or 3

it couldn't be 4, because that wouldn't be sum of 4, that would be all of 4

#4**+4 **

2+2==4. Itβs a bit boring, but hopefully the way was somehow enlightening. Anyhow, 2=π(π(0))2=S(S(0)) and 4=π(π(π(π(0))))4=S(S(S(S(0)))).

2+2=π(π(0))+π(π(0))βΉ2+2=S(S(0))+S(S(0))βΉ

2+2=π(π(π(0))+π(0))βΉ2+2=S(S(S(0))+S(0))βΉ

2+2=π(π(π(0))+1)βΉ2+2=S(S(S(0))+1)βΉ

2+2=π(π(π(π(0))))=4
