decimaM.13.122:The arabic numeral "10" has been written 01, placing the numeral indicating units to the left of the numeral indicating tens. Treatises on computation instruct writers
to begin writing numerals with the units and to proceed with the tens, hundreds, etc., moving, as Arabic scripts do, from
right to left. The form here reflects that order of digits, but not that direction of the script. Cf. The Earliest Arithmetics in English, ed. Robert Steele. EETS ES 118, pp. 1-8. discriptio de dowell
