Cuneiform numbers


Cuneiform numbers were written using a combination of just two signs: a vertical wedge for '1' and a corner wedge for '10'. Handwriting varied as much in Old Babylonian times as it does now but the basic system of numbers is illustrated below.
 
 
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
17 18 19 20
30 40 50 60

Some common variants are
 
for 4
for 7
for 8.

Occasionally, 19 was written as something like  , meaning 20 - 1, although there are a huge number of minor variations in the way this sign is written.
 

Additionally, there were special signs for some common fractions.  These were used when the numbers stood for metrological quantities, such as 1/2 gin.
 
1/2
1/3
2/3
5/6
