Because the information necessary for that is already available from the subnet mask WITHOUT the bitwise AND, e.g., with 255.255.255.0 or 1111 1111.1111 1111.1111 1111.0000 0000, you count the amount of 1s, which in this case is 24 and corresponds to that appendix in the CIDR notation. At this point, you already know that you only need to consider those first 24 bits from the IP address, making the subsequent bitwise AND redundant.

On a technical level, the bitwise operation is all that is needed. It is one calculation of the simplest kind. A CPU can do it in 1 tick. That's why they invented it this way.

The other way that you described is the super extra ultra lengthy complicated - and maybe redundant - thing.

but would it not be easier to

Seriously?

All the world is doing it for decades, and we never thought of asking you how to do it right?

No weapons, just you and the squirrels.

My teeth are terrifying weapons, chrrrr!!

In a fight to death, my only problem would be that I get tired from the fighting, sooner or later. And then they could do some real harm.

On the other hand, I assume that they are not smart enough to apply any special tactics that make use of this, or of their large number (coordinated action etc.)

So I would trust myself against maybe 50 of them.

Excuse me

No, I do not excuse foul language, and this will be my last response for you.

If that explanation is some variation of "This authoritarian that said

The question here was about a driving test, not about some mechanical science. Case closed.

The outside is the easy part (unless there is thick ice): use the water spray with the wipers. In the winter, the water contains a thawing solvent.

For the inside, what I personally do in the winter: before parking my car in the evening, I open all the windows for a few minutes to let the cold air in (also switch off the heating). Cold air is very dry. So it does not mist up (most times) in the morning.

Möglicherweise haben sie die Regeln irgendwann geändert, das weiß ich nicht.

I hit a barn with a dump truck because the clutch pedal failed to disengage the clutch

Then your right foot was not firmly on the brake, see step 1.

learning should be a basic human right!

Education is a basic human right (except maybe in Usa, then it should be one there)

I guess they just don't use broken cars in the driving test.

I definitely agree that

I recommend to make yourself familiar with the concept of some things being true even if you don't agree to them.

There are even things that still remain after nobody believes in them anymore (that is one definition of 'reality').

OK so now I know again that I don't have one :)
