sowiso logo Basic maths plus
Algebra, precalculus and calculus for college and university students. Contains topics ranging from numbers to differentiation, integration and geometry. It covers all topics from the standard Basic Mathematics course, and some extra topics on sequences and series, limits and geometry. And it contains some extra exercises on the Bloom levels Application and Analyses, where the basic material is more on a knowledge and comprehension level, and just a little analyses.
