Die Autoren beschreiben die Entstehung, Entwicklung und Wandlung der Algebra als Teil unserer Kulturgeschichte. Ursprünge, Anstöße und die Entwicklung algebraischer Begriffe und Methoden werden in enger Verflechtung mit historischen Ereignissen und menschlichen Schicksalen dargestellt. Ein erster Spannungsbogen reicht von den Frühformen des Rechnens mit natürlichen Zahlen und Brüchen zur Lösung einfacher Gleichungen bis hin zur Lösung von Gleichungen dritten und vierten Grades in der Renaissance. Von den misslungenen Versuchen zur Lösung allgemeiner Gleichungen höheren Grades im 17 Jh. zieht sich ein weiterer Bogen zu den genialen Ideen des jungen Galois und den berühmten Beweisen des Fundamentalsatzes der Algebra durch C.F. Gauß. Die Wandlung der Algebra von der Gleichungslehre zur Theorie algebraischer Strukturen wird danach ebenso beschrieben, wie die völlig neuen Akzente, die die Computeralgebra in neuester Zeit gesetzt hat.
