Hopefully this may speed your groking of the forking torturing Y Combinator a little bit.

Disclaimer: I don't assert what I say here is accurate, or even correct (I'm not authorative, obviously), but it's my understanding and I'm sharing in the hope that someone who also struggles on the Y Combinator may benefit a tad.

Prerequisite Understandings

In Lambda Caculus, everything is a Lambda Caculus (Anonymous function that takes one parameter). And the best thing is that, ... drump roll ..., it's Turing Complete. So theoretically, it can caculate anything a computer can.
In this note, I use the term function, which (I think) means Lambda Caculus, to sound (at least to myself) more accustomed.

The definition of Y Combinator

Y = λf.(λx.f (x x)) (λx.f (x x))

Multiplication from Scratch

Imagine you need to implement (integer) mulitplication in code. Maybe you are on a system which doesn't have it or something. How to do this, and what is the minimal set of operators that are required?

Repeated addition

The most obvious way to do multiplition is through repeated addition. To get the answer to 56 x 67 you add 56 to itself 67 times (or 67, 56 times - the order doesn't matter).

This is simple to implement if we assume for the moment that both a and b are positive (we will deal with negative integers later)

	public class Sample
	{
	[Test]
	public void MetadataSample()
	{
	Items.ItemA.ShouldEqual(Items.ItemA);

	Items.ItemA.Description.ShouldEndWith("Description for A");
	}
	}

	Write-Host "Synchronizing your docker time."

	$principal = New-Object Security.Principal.WindowsPrincipal([Security.Principal.WindowsIdentity]::GetCurrent())
	if ($principal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
	$name = (Get-VMIntegrationService -VMName DockerDesktopVM \| Where-Object { $_.Id.StartsWith("Microsoft:") -and $_.Id.EndsWith("\2497F4DE-E9FA-4204-80E4-4B75C46419C0") }).Name # "Time Synchronization" for English Windows
	Get-VMIntegrationService -VMName DockerDesktopVM -Name $name \| Disable-VMIntegrationService
	Get-VMIntegrationService -VMName DockerDesktopVM -Name $name \| Enable-VMIntegrationService
	echo $name
	Write-Host "Time synced!"
	Read-Host -Prompt "Press Enter to exit."
