Math in HTML

The following is a test of mathematics in pure HTML with no MathML or images involved:

1   2

= 0.5

√

2

= 1.414213562373…

2ℵ0 = c

20א = c

eπi + 1 = 0

ζ(s) =

∞ ∑ n = 1

.1.  ns

=

∞ ∏ k = 1

.1.  1 –  .1.  pks

Addendum: The above looks slightly better in Firefox than in Explorer.

Another Addendum: After reading this (seen via Geek Press), I had to add the following:

1   2

< ⌊mod(⌊

y   17

⌋2–17⌊x⌋ – mod(⌊y⌋,17), 2)⌋
