In his mathematical papers, Newton applies his algorithm for the equation -rx+
Example, [1st.] -rx+In modern day notation, Newton's formula involves partial derivatives with respect to x and y. He multiplies ''each terme of y 
eqat: by so many units as x hath dimensions in y 
terme'' and ''divides it by x & multiply by y for a numerator.''
In other words, he takes f  multiplies by x
and y and divides by x, (  , for
a numerator. Then he multiplies ''each terme of y
equation by soe many units as y hath dimensions in each terme & divide
it by -y for a denom:'' In modern mathematical English, he means,
take f  multiply by y and its negative inverse,
(  for a denominator. This of course results in
the equation  =-y*  .

+yy=0. He writes:
in y = -ry+ 
.
. Therefore
