By the way, this must be a mistake:
This is a clearly a byproduct of the right-to-left language of the designers of these systems
[edit oh, numbers! thanks! i was thinking about algebra.]
1237 + 4567
7+7 = 14 = 4
3+6 + 1 = 10 = 0
2+5+1 = 7
1+4 = 5

Example:
(+ 5 (* 10 x))
Compare to Reverse Polish Notation (used in Hewlett-Packard calculators and elsewhere), which would express the above as:
10 x * 5 +Even in Arabic, numbers are the exception, written from left to write.

You will notice the number sequencing, although slightly different looking, is the same as in Western orthography. Why? Arabs took their numbering system from the Indians, and adapted it.
This is true in modern times, but in antiquity Arabic and Hebrew numerals were written right-to-left.
In our system (and in the Arabic "Indian" system, as pointed out by a fellow reply) numerals are written with the least significative figure to the right, so in that sense it's like com.twitter@holysee.
However, the author has acknowledged that there was a minor error in the post, so this is a case of a retrofitted explanation :-)
In fact, notations do not have to be consistent about digit significance. See, for example, US dates (9/11/2001) or German (and Arabic) long-form of most two digit numerals, which are read backwards, as in "four and twenty blackbirds" (happy to be corrected about Arabic...).
