There was this estimation technique one of the Sixty Symbols professors talked about, where you do all of the calculations, but you only keep one significant digit. It's something you can do quickly in your head while conversing with someone, but tells you pretty reliably if something is feasible.

I feel this was a response to this recent submission as perhaps an example of a math text that is less traditional? (Could be interesting to look at the discussion and see how this text holds up?)

Why do many math books have so much detail and so little enlightenment? (2010)

When the first digit becomes 1 keep two digits. A small effort for much higher precision. (Something to do with Benford's Law? Maybe.)
