I don't know about you, but when I do math without a calculator, my accuracy also drops precipitously whenever they add a digit.

Do you have self awareness to anticipate the drop in your accuracy and refuse to perform the operation?

[falcor84]

I do anticipate it, but in the situations I'm asked to do such calculations, I don't usually have the option of refusing, nor would I want to. For most real would situations, it's generally better to arrive at a ballpark solution than to refuse to engage with the problem.

Ballpark solution is in a way refusing...
