So if a square can fit in a circle does that make it an oval. how come we get in a car but on a bus.

If i have two eggs in a bowl and then put them in another bowl how many eggs do i have?

Q1. No all three are their own shapes some shapes can fit inside each other though but doesn’t make it a new shape
Q2. We are getting in because we are opening the doors and immediately sitting down but we get on a bus because we are stepping on to it not getting in it like we would a vehicle although it wouldn’t make sense to some it is the truth.
Q3. You’ll still have two eggs nothing is changing when you switch it to the other bowl the only thing that is changing is your bowls but the amount of eggs you have which are two will stay the same.

Wait u answered your own question
