funny story, quoting:
```
"Tell me," he said, "how were you able to do that cube-root problem so fast?"
I started to explain that it was an approximate method, and had to do with the percentage of error. "Suppose you had given me 28. Now the cube root of 27 is 3 ..."
He picks up his abacus: zzzzzzzzzzzzzzz— "Oh yes," he says.
I realized something: he doesn't know numbers... Furthermore, the whole idea of an approximate method was beyond him, even though a cubic root often cannot be computed exactly by any method.
