How to use it. yf þe figure, þe quych schalle be multiplied, be euene as mych as þe diget be, þe quych þat oþer figure schal be multiplied, as two tymes twayɳ, or thre tymes 3. or sych other. The way to use the Multiplication table. loke qwere þat figure sittes in þe lyft side of þe triangle, & loke qwere þe diget sittes in þe neþer most rewe of þe triangle. & go fro hym vpwarde in þe same rewe, þe quych rewe gose vpwarde til þou come agaynes þe oþer digette þat sittes in þe lyft side of þe triangle. And þat nounbre, þe quych þou leaf 155 b. fyn*des þere is þe nounbre þat comes of the multiplicacioɳ of þe 2 digittes, as yf þou wold wete qwat is 2 tymes 2. loke quere sittes 2 in þe lyft side in þe first rewe, he sittes next 1 in þe lyft side al on hye, as þou may se; þe[n] loke qwere sittes 2 in þe lowyst rewe of þe triangle, & go fro hym vpwarde in þe same rewe tylle þou come [a-ȝenenes] 2 in þe hyer place, & þer þou schalt fynd ywrite 4, & þat is þe nounbre þat comes of þe multiplicacioɳ of two tymes tweyn is 4, as þow wotest welle. yf þe diget. the quych is multiplied, be more þan þe oþer, þou schalt loke qwere þe more diget sittes in þe lowest rewe of þe triangle, & go vpwarde in þe same rewe tyl[10] þou come [a-nendes] þe lasse diget in the lyft side. And þere þou schalt fynde þe nombre þat comes of þe multiplicacioɳ; but þou schalt vnderstonde þat þis rewle, þe quych is in þis verse. ¶ In digitum cures, &c., noþer þis triangle schalle not serue, bot to fynde þe nounbres þat comes of the multiplicacioɳ þat comes of 2 articuls or composites, þe nedes no craft but yf þou wolt multiply in þi mynde. And leaf 156 a. *þere-to þou schalt haue a craft afterwarde, for þou schall wyrch with digettes in þe tables, as þou schalt know afterwarde. versus.
To multiply one Composite by another.
¶ Postea procedas postremam multiplicando
[Recte multiplicans per cunctas inferiores]
Condicionem tamen tali quod multiplicantes
Scribas in capite quicquid processerit inde
Sed postquam fuit hec multiplicate figure
Anteriorentur serei multiplicantis
Et sic multiplica velut isti multiplicasti
