'''Counting Rod Numerals''' is a [[Unicode block]] containing traditional Chinese [[counting rods|counting rod]] symbols, which mathematicians used for calculation in ancient China, Japan, Korea, and Vietnam. The orientation of the Unicode characters follows [[Song dynasty]] convention, with digits represented as horizontal lines, and tens represented as vertical lines, which differs from [[Han dynasty]] practice which represented digits as vertical lines, and tens as horizontal lines.<ref>{{ Citation | title=The Unicode Standard, Version 15.0 – Electronic edition | url=https://www.unicode.org/versions/Unicode15.0.0/ch22.pdf#G12367 | year=2022 | pages=869–870 | publisher=Unicode, Inc.}}</ref>
The block also contains five ideographic [[tally mark]]s, based on the five strokes of the character [[wikt:正|正]], which are widely used in East Asia. There are also two characters for use in representing traditional European tally marks (only Tally Mark One and Tally Mark Five are encoded, with tally numbers two through four intended to be represented as a sequence of two through four Tally Mark One characters).
