[Commentary:
The verses on this page describe the rules for operating with
positive quantities ('more') and negative quantites ('lesse').
The first verse sets out the rules for multiplication.
The second and third verses deal with subtraction of a negative quantity from a negative quantity,
where the result may be either positive or negative.
Like folios Add MS f. f. , which follow soon after it, this one appears to be based on Viète's In artem analyticen isagoge (Viete 1591, Chapter IV, Precepts II, . ]

If more by more must needes make more
Then lesse by more makes lesse of more
And lesse by lesse makes lesse of lesse
If more be more and lesse be
Then lesse by more makes lesse of more
And lesse by lesse makes lesse of lesse
If more be more and lesse be
Yet lesse of lesse makes lesse or more
The which is best keep both in store
If lesse of lesse thou you wilt make lesse
Then pull bate the same from that is
The which is best keep both in store
If lesse of lesse thou you wilt make lesse
Then pull bate the same from that is
But if the same thou you wilt make more
Then add the same to it to that is the sign of more
The signe rule of more is best to use
Except some Yet for some cause the do other choose then it refuse
For So Yet both are one, for both are true
of this inough and so
Then add the same to it to that is the sign of more
The signe rule of more is best to use
Except some Yet for some cause the do other choose then it refuse
For So Yet both are one, for both are true
of this inough and so
