Sheet 1

This block of work corresponds to Weeks 1 and 2 (3 lectures), and is designed for tutorials in Week 3. It's about the real numbers, arithmetic, ordering, and modulus. Lecture notes Sections 2, 3, 4, 5, 6, 7.

The problems sheet is below as a pdf attachment, and is also available as a Sheet 1 Moodle version for those who find that more convenient/accessible.

There are also optional activities for this block of work: a quiz (Sheet 1) Starter 1 - Axioms for R and (Sheet 1) Starter 2 - Name that axiom and (Sheet 1) Pudding - Field or Not a Field? . There's also an extra optional quiz Highlights of the Greek alphabet. It's not directly related to this block of work as we shan't use Greek letters till slightly later in term, but it's available to you at any time and might be useful if you don't yet feel confident with naming and writing Greek letters.
