# An Invitation To Mathematics

Duration: 16:21:00
Lectures: 36
Level: Beginner This course is an introduction to the ideas and methods of mathematics. The only prerequisite is some familiarity with
topics in a typical high school mathematics curriculum. We will revisit many of these from a more conceptual viewpoint and
through numerous examples. Special emphasis will be laid on the interconnections between seemingly disjoint topics. This
course seeks to go beyond the “procedures-to-solve-routine problems” approach of a typical school curriculum to offer a
glimpse of what mathematics is really about. It should be suitable for high school students, lower undergraduates,
teachers at various levels, or others with a keen interest in mathematics.
