Default Re: Math trivia

While I agree it's a confusing system for naming paper sizes, your post actually makes it clear that it's not unmathematical. The multiplicative term precedes the 'A', and the negative exponent follows it. As a result, there's more than one way to refer to each paper size:

1/2A-1 = A0 = 2A1 = 4A2
1/4A2 = 1/2A3 = A4 = 2A5

It's not unlike the notation used in scientific calculators, e.g. 3.782e+36
