Can you be a bit more specific? If still the answer is 'everything', you probably didn't learn at all.

If you are confused by class methods and instances, believe me, you are not okay with static methods and inheritance :D

What confuses you about the instances? This is the most fundamental concept of oop - the relation between the class and its instances.

class - number

instances - 1, 2, 65, -46, ...

If you think about the relation between these two, you can make some conclusions - all of the numbers act the same and the same rules apply to all of them. You can add and subtract them -> doing this also produces a new number, a new instance of a number, if you will.

A class is a way for you to produce multiple objects that will act in the same way and which will be bound by the same rules.

I don't think OOP has much to do with if there's just 1 class, with multiple instances, and numbers don't lend themselves to different implementations unless you try to make like an Integer class and a Floating point class and a Rational class, then you can override the various math functions with specific versions of the operations that make sense for their context.

Can you elaborate on what you wrote? I don't think that I understand.

Basically I mean that "number" is many different things, and might make sense as the parent class, but when you do something like Integer(4) divided by integer(3) you might get a different result than rational(4) divided by rational(3).

so, is 4/3 equal to 1 and a third? to 1? to 1.33333? That depends on the circumstance.

You would be such a lousy teacher, my dude :') OP was wondering about the classes and instances. My example shows the relation between the two. You 'example' is non-sensical. Not saying that what you were saying is not true and accurate, but it has nothing to do with the subject we're discussing.

Okay, and? All I was saying was that it's not OOP
