[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.

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

Then pull bate the same from that is
The which is best keep both in store

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
