yf it be egall{e} or even the figure sette beside, put in his place a
cifre. And yf it be more put away þ{er}fro als many of vnitees the lower

And yf it be lesse, by-cause the more may not be w{i}t{h}-draw ther-fro,
borow an vnyte of the next figure that is worth{e} 10. Of that .10. and
of the figure that ye wold{e} have w{i}t{h}-draw fro be-fore to-gedre
Ioyned{e}, w{i}t{h}-draw þe figure be-nethe, and put the residue in the

And yf the figure wherof me shal borow the vnyte be one, put it a-side,
and write a cifre in the place þ{er}of, lest the figures folowing faile

And yf the vnyte wherof me shal borow be a cifre, go ferther to the
