{{main|Aegean numerals}}

These numerals follow a decimal system: units are represented by vertical dashes, tens by horizontal dashes, hundreds by circles, and thousands by circles with rays. There are special symbols to indicate fractions and weights. Specific signs that coincide with numerals are regarded as fractions;<ref>{{harvnb|Packard|1974|pages=23–24}}</ref> these sign combinations are known as ''klasmatograms''.<ref>{{cite journal |last1=Proust |first1=Christine |title=Numerical and Metrological Graphemes: From Cuneiform to Transliteration |journal=Cuneiform Digital Library Journal |date=June 22, 2009 |url=https://cdli.mpiwg-berlin.mpg.de/articles/cdlj/2009-1 |access-date=January 23, 2024}}</ref>

Integers can be read and the operations of addition, subtraction, multiplication, and division are quite straightforward, similarly to [[Roman numerals]].<ref>{{cite journal |last1=Anderson |first1=W.

=== Fractions ===
There is a lack of scholarly agreement about signs, generally called klasmatograms, for Linear A fractions.<ref>{{cite journal |last1=Billigmeier |first1=Jon C. |title=Linear A Fractions: A New Approach |journal=American Journal of Archaeology |date=1 October 1973 |volume=77 |issue=1 |pages=61–65 |doi=10.2307/503234 |jstor=503234 |s2cid=191382050 |url=https://www.journals.uchicago.edu/doi/pdf/10.2307/503234 |access-date= |language=en |issn=0002-9114|url-access=subscription }}</ref><ref>{{cite journal |last1=Bennett |first1=Emmett L. |title=Linear A fractional retractation |journal=Kadmos |date=1 January 1980 |volume=19 |issue=1 |pages=12–23 |doi=10.1515/kadmos-1980-0104 |s2cid=163961065 |url=https://www.degruyter.com/document/doi/10.1515/kadmos-1980-0104/html |access-date= |language=| issn=0022-7498|url-access=subscription }}</ref><ref>{{cite journal |last1=Schrijver |first1=Peter |title=Fractions and food rations in Linear A |journal=Kadmos |date=1 July 2014 |volume=53 |issue=1–2 |pages=1–44 |doi=10.1515/kadmos-2014-0001 |s2cid=164932371 |url=https://www.degruyter.com/document/doi/10.1515/kadmos-2014-0001/html |access-date= |language= | issn=0022-7498 |url-access=subscription }}</ref><ref>Giulio Facchetti, "Linear A metrograms", Kadmos, vol. 33, no. 2, pp. 142–148, 1994</ref> In 2021 Corazza et al. proposed the following values, most of which had been previously suggested:<ref name="Corazza">{{cite journal |last1=Corazza |first1=Michele |last2=Ferrara |first2=Silvia |last3=Montecchi |first3=Barbara |last4=Tamburini |first4=Fabio |last5=Valério |first5=Miguel |title=The mathematical values of fraction signs in the Linear A script: A computational, statistical and typological approach |journal=Journal of Archaeological Science |date=2021 |volume=125 |pages=1–14 |doi=10.1016/j.jas.2020.105214|s2cid=225229514 |doi-access=free |bibcode=2021JArSc.125j5214C |hdl=11585/789546 |hdl-access=free }}</ref>

Other fractions are composed by addition: the common JE and DD are {{frac|3|4}} and {{frac|1|3}} ({{frac|2|6}}), BB = {{frac|2|5}}, EF = {{frac|3|8}}, etc. (and indeed B {{frac|1|5}} looks like it might derive from KK {{frac|2|10}}).  L, Y, and Ω are [[hapax legomena]] (only occur once) and it has been proposed that glyph L is spurious.<ref name="Corazza" />

Several of these values are supported by Linear B. Although Linear B used a different numbering system, several of the Linear A fractions were adopted as fractional units of measurement. For example, Linear B DD and (presumably AA) are {{frac|1|3}} and {{frac|1|12}} of a ''lana'', while K is {{frac|1|10}} of the main unit for dry weight.<ref name=Corazza/>
