**Section 4 - Problems on Arithmetic Operations and Inequalities in a Field.**

The questions here are very basic, so I'm not going to bother going through them. I will in fact go through the proof of Corollary 7, and Question 5, (iv) and (v). Unfortunately not today though.

Section 5 - Natural Numbers and Induction.

Section 5 - Natural Numbers and Induction.

A discussion of Natural Numbers was done. The First and Second Induction Laws were introduced, which we call Weak and Strong at school. Examples using induction were done, along with some Theorems.

**Section 6 = Induction.**

Some more definitions, mostly recursive. Some basic stuff that can help you with proofs that are to come.
