About

If the timings of the sessions do not suit you, then please send me a message either directly or through the series chat. I plan for this to be a conversational series where we investigate how one actually goes about constructing the number systems we use throughout Calculus. In this series, I plan to construct the natural numbers, integers, rational numbers and (possibly) the real numbers. The real numbers are fairly complicated to understand. Consequently, I will only cover this construction if there is any demand for it and how strong the audience is in mathematical maturity. I expect that the audience has some familiarity with basic proof writing. Though if needed, I can quickly cover this at the beginning of the series. That's it, bye for now!

✋ ATTENDANCE POLICY

Try not to miss sessions for the reason that sessions are highly dependent on previous ones.

If you cannot make a session, please notify me about it in either the series chat, or a private chat. This way I can plan a catchup session before the next one.

Session 1

Orientation

Let's get to know each other! We will cover basic logic and proof writing needed for this series. If you feel okay with proof writing then this session can be skipped.

Session 2

Other Topics

Now that we have a basic idea on how the natural numbers are made, we are in a position to discover some basic properties that the natural numbers have!

Session 3

Other Topics

Here we talk about the need for such constructions and get some basic scaffolding built so we can get a footing on how the natural numbers are constructed! In order for this to happen, we must try to forget everything we know about numbers. This is rather a difficult task to do! Only allow our intuition to take over and not let any advanced tricks such as the rules of algebra take over our thinking!

Session 4

Other Topics

We will continue looking at multiplication of natural numbers and look at exponentiation as well. From there, we will move on to the construction of the integers. This will be done by introducing subtraction as an operation on the integers.

Session 5

Other Topics

We will finish our discussion of the integers and then move onto the rational numbers.
