In Zen math, 2 + 2 = 4 as any schoolchild knows.
However, 2 + 2 = 2 too, and = 3,4,5.
2 - 2 = 9 all down the line.
2 = 4 = 7 = Buddha Heaven.
And all or any numbers added, divided, subtracted or divided are simply 1 at the start, middle and end.
.00001 = the 10,000 things

All the columns always in balance, whatever is put in them.
Something like that. :p
