TL;DR: Instead of labouriously computing \(c = \sqrt{a^2 + b^2}\), we can mentally calculate using the alpha-max plus beta-min algorithm, by estimating
\[\hat{c} = \mathrm{max}\left(a, 0.9a + 0.5b \right)\]
and this will be very close to the actual \(c\). This is useful for adding up sources of variance, or figuring out radiuses, or other such things.
