Quick Summary

In In artem analyticem isagoge (1591), François Viète introduced a systematic approach to algebra, earning him the title "father of modern algebraic notation". This work is considered by some to resemble a modern elementary algebra textbook. Viète's key innovation was the use of symbols for unknowns (vowels) and known quantities (consonants), allowing for greater generality in solving equations. This marked a significant step towards the modern concept of an equation as a distinct mathematical entity. Viète's methods facilitated the study of symbolic solutions to algebraic equations and contributed to the development of the theory of equations.123

Viète and the formal equation
A main innovation of Viète’s In artem analyticam isagoge (1591; “Introduction to the Analytic Art”) was its use of well-chosen symbols of one kind (vowels) for unknowns and of another kind (consonants) for known quantities. This allowed not only flexibility and generality in solving linear and quadratic equations but also…
