〈 math 〉〈 math 〉 The summe of multiplication, when you would multiplie any num∣ber by 10. you muste onelye adde one cipher vnto all the number.

And to be briefe, when the laste figure of the multiplier is. 1. and all the rest be ciphers, adde so many ciphers to your multiplicande, as ther shalbe foūd in your multiplier

likewise those of that multiplicande, then shall you putte those cyphers a part, and multiplie the signifiyng fi∣gures of the one by the signifiyng fi∣gures of the other. Than adde vnto the product of that multiplication, all the ciphers whiche you dyd before put a part. As if I would multiply. 46000 by 3500. I put apart the thrée ciphers of the fyrste, and twoo ciphers of the seconde numbers. And then I multi∣ply fourtie sixe by 35. and thereof com∣meth 2610: vnto the whiche I add the 00000. and then the whole producte will be. 161000000. 〈 math 〉〈 math 〉
