What are the counting numbers divisible by 3?

A number is divisible by 3, if the sum of its all digits is a multiple of 3 or divisibility by 3. Sum of all the digits of 54 = 5 + 4 = 9, which is divisible by 3. Hence, 54 is divisible by 3. Sum of all the digits of 73 = 7 + 3 = 10, which is not divisible by 3.

Why are even numbers the same as positive even numbers?

As sets the positive numbers and the positive even numbers are “the same” (that is are in bijection) because you can take 1,2,3,… and just rename1 to 2, and 2 to 4, and n to 2n, and you’ve just renamed all the elements and got the even numbers!

How do you measure the size of a subset of numbers?

For example, a common way to measure “size of a subset of the natural numbers” is by its “density.” That is you look at the first N numbers and calculate what fraction of them are in your set, and then take the limit as N goes to infinity (warning for sufficiently complicated sets this limit might not exist).
