<pre class="moz-quote-pre" wrap="">Séamas made a really interesting remark:
I always thought it was obvious, or at least fairly intuitive.
A < B: A is less than B; A > B: A is greater than B.
Me too! I've been taught (brainwashed?) from childhood to interpret "<" as less-than. But yesterday when I reflected on it, it occurred to me that there is nothing at all obvious or intuitive about using "<" to denote less-than. Why would two non-parallel lines terminating at the meeting point denote less-than? Stated another way, why would a "v" turned sideways denote less-than?
I guess someone (French mathematician Pierre Bouguer, British logician John Wallis) just made it up.

<p>When I was learning the signs, they said to remember it because
the *small* end points to the *small* number and the *big* end to
the *big* number. That seems pretty intuitive to me. Now, that
gives you a model in your head that is graphical and doesn't align
with words "less than" and "greater than" directly; took me a
little while to completely associate the symbols with the words
directly.</p>
