In the early modern period, a crucial transformation occurred in the
classical conception of number and magnitude. Traditionally, numbers
were merely collections of discrete units that measured some multiple.
Magnitude, on the other hand, was usually described as being continuous,
or being divisible into parts that are infinitely divisible. This
traditional idea of discrete number versus continuous magnitude was
challenged in the early modern period in several ways.
This detailed study explores how the development of algebraic symbolism,
logarithms, and the growing practical demands for an expanded number
concept all contributed to a broadening of the number concept in early
modern England. An interest in solving practical problems was not, in
itself, enough to cause a generalisation of the number concept. It was
the combined impact of novel practical applications together with the
concomitant development of such mathematical advances as algebraic
notation and logarithms that produced a broadened number concept.
