_M._ Well the{n} to go forth, in the nexte space I fynde one counter
which I remoue forward but take not vp, but do (as in such case I must)
set downe the greater halfe of my multiplier (seyng it is an odde
no{m}ber) which is 182, {and} here I do styll let that fourth place
stand, as yf it were y^e fyrst:
------------+-----------+--o-o-o--+--o---------
| | o | o
------------+-----------+--o------+--o-o-o-----
| | o |
-||---------+-----------+---------+--o-o------- [<-]
| | | o
-----o-o-o--+-----------+---------+------------
o | | |
-----o------+--o-o-o-o--+---------+------------
o | | |
------------+--o-o------+---------+------------
as in this fourme you se, where I haue set this multiplycatio{n} with
y^e other: but for the ease of your vndersta{n}dynge, I haue set a
lytell lyne betwene them: now shulde they both in one su{m}me stand
thus.

[*123a] Howe be it an other fourme to multyplye suche cou{n}ters i{n}
space is this: Fyrst to remoue the fynger to the lyne nexte benethe y^e
space, {and} then to take vp y^e cou{n}ter, {and} to set downe y^e
multiplyer .v. tymes, as here you se.
