Learn the fundamentals of analysis and inequalities in this free course. Discover rational and irrational numbers, solving inequalities, and proving inequalities. Explore the concept of least upper bounds and how they define arithmetic operations on real numbers. Enhance your mathematical skills today.

This free course is an introduction to analysis which looks at real numbers and their properties, with a particular emphasis on inequalities. Section 1 starts by revising rational numbers and their decimal representations. Then, real numbers are introduced as infinite decimals. Section 2 looks at rules for manipulating inequalities and finding the solution set of an inequality. Section 3 looks at various techniques for proving inequalities. Section 4 introduces the concept of a least upper bound. Section 5 looks at how least upper bounds can be used to define arithmetic operations on the set of real numbers.
