About 1780, Mozart Acquired A Textbook For Math, One That Presented Arithmetic And Algebraic Principles, Tables, And Practice Exercises All Within A Single, Comprehensive Volume: Fundamentals Of Arithmetic And Algebra (Anfangsgründe Der Rechenkunst Und Algebra) By Joseph Spengler (1736-1776). Spengler Was A Jesuit Priest And His Volume Was Published In Augsburg, The Home Town Of Jesuit-Educated Leopold Mozart. The Book First Appeared In 1772 And Then Went Through Six Reprinting Before Being Revised And Expanded In 1800. Mozart Owned A Copy Of The Third Edition (1779), Possibly Acquiring It When He Passed Through Augsburg, The Home Of His Cousin Basle, In January 1779, Or More Likely Later When Living In Salzburg Or Vienna. Mozart Held On To The Volume Until He Died. It Was One Of Forty Books In The Probate List Of His Estate (1791) And One Of The Few Treating A Scientific Subject.[See The Long Essay Musings On Mozart And Math By Craig Wright, On The Internet).
