And þis same nombur þ{o}u hadyst or þ{o}u began to medye, as þ{o}u mayst see in þe secunde Ensampul þat þou had in þe 4 case of mediacioɳ, þat was þis: when þ{o}u had mediet truly all{e} the nombur, a p{ri}ncipio usque ad fine{m}. þ{o}u schalt haue of þat mediacioɳ þis nombur 5 102. Now doubul 1. þat wel be 2. do away 1 & sett þ{ere} 2. þen doubul 0. þ{a}t will be noȝt. þ{ere}for{e} take þe 5, þe quych stondes ou{er} þe next figur{es} hed, & doubul it, & þat wol be 10. do away þe 0 þat stondes betwene þe two fig{u}r{i}s, & sette þ{ere} in his stid 1, for þ{a}t 1 now schal stonde in þe secunde place, wher{e} he schal betoken 10; þen doubul 2, þat wol be 4. do away 2 & sett þere 4. & [*leaf 153a] þou schal haue þus nombur 214. þis is þe same nu{m}bur þat þ{o}u hadyst or þ{o}u began to medye, as þ{o}u may see.
