Part I: First StepsΒΆ

The first part of the course consists of the first 9 lectures. One strength of computer algebra is the wide range of number types and arithmetic that go beyond what is offered by the computer arithmetic. In addition to exact rational and arbitrary multiprecision floating-point arithmetic, we cover complex and algebraic numbers. For the latter, we introduce the basics of expressions, and in particular polynomials with coefficients over any number field.
