Rīmagiefung (on Nīƿenglisce hātte algebra) is dǣl rīmcræftes be þǣre cneordlǣcinge þāra laga of ƿeorcunge and gesibbnessum, and þǣm timbrum and oncnāƿnessum þe arīsaþ from heom, ēac besetednessum, manigsetednessum, efenƿeorðfindungum, and rīmagiefunglicum endebyrdnessum. Andefen eorþmetes, arāflunge, stōƿlāre, tellingalāre, and rīma flītcræftes is rīmagiefung ān þāra hēafodlicena dǣla smǣtes rīmcræftes.

Þā þā Plato cōm, Crēcisc rīmcræft hæfde gefēred micele andƿendunge.

Þās geƿritu standaþ be þǣre arāflinge rīmagiefunglicra efenƿeorþfindunga.

Tō ungelīcnesse, þæt mǣste dǣl Egyptiscena þisre tīde, and Crēciscena and Cīniscena rīmlārmanna in þǣm 1 þūsendgēare fōre Crīste, geƿunelīce arāflede sƿelca efenƿeorþfindunga þurh eorþmetlica endebyrdnesse, sƿelce þās amearcod in þǣm Rhind Rīmlāriscan Papyrus, Euclides Gesceaft, and Þā Nigone Hēafodƿearda on þǣm Rīmcræfte.
