These are difficult, and I’m not sure I grasp all of their aspects. If you’d like, feel free to expand or correct me in comments.
There are four central aspects to the Latin numeral:
- The cardinal: ūnus, duo, trēs, quattuor
- The ordinal: prīmus, secundus, tertius, quārtus
- The distributive: singulī, bīnī, ternī, quaternī
- The adverb: semel, bis, ter, quater
The distributive describes how many each or how many apiece. It’s a numeral of rate.
- The children received candy, one each: puerī mellīta accēpērunt, singula singulīs
Note a few things:
- The distributive numerals are plural adjectives, here matching mellīta (singula) and puerī (–> puerīs) (singulīs)
- They decline like the plural of bonus, -a, -um
The distributive are used to multiply, featured in the formula numeral adverb + distributive:
- 2 x 2 = bis bīna
- 3 x 7 = ter septēna
The poets also use distributives in place of cardinals, to express sets.
- He threw two shafts (in a set): bīna hastīlia torsit.

A few typos (I think?), where ē should be instead of e –
trīcenī -> trīcēnī
vīcenī -> vīcēnī
vīcenī singulī, vīcenae singulae -> vīcēnī singulī, vīcēnae singulae
Also, missing ‘n’:
quadrigēnī -> quadringēnī
septigēnī -> septingēnī
octigēnī -> octingēnī
thanks!
