Integers can be implied decimals or fractions. 3 is the same as 3.0 3 is the same as 3/1 As a general rule, decimals and fractions are distinct from integers.

If they can be same 15*15 =225 if they have to be distinct 13*17 =221
The set of positive integers is {1,2,3,4,5,...}. When referring to numbers, distinct simply means different from each other e.g. 2,6,7 and 9 are distinct positive integers but 2,6,6 and 9 are not distinct since two of them are equal.
To determine the number of positive integers less than 1000 with distinct digits and are even, we need to consider the possible combinations of digits. Since the number must be even, the last digit must be even, giving us 5 options (0, 2, 4, 6, 8). For the hundreds digit, we have 9 options (1-9), and for the tens digit, we have 8 options (0-9 excluding the hundreds digit and the last digit). Therefore, the total number of such integers is 5 * 9 * 8 = 360.
There are 120 of them.
9*9*8*7 = 4536
10*9*8=720

Any set with fewer than or more than 20 distinct elements cannot represent the set of integers from 1 to 20.

'let s be a collection of 16 integers, each from 1 to 30 inclusive. show that there must exist two distinct elements in s which differ by exactly 3. 'let s be a collection of 16 integers, each from 1 to 30 inclusive. show that there must exist two distinct elements in s which differ by exactly 3.

Integers and mixed numbers are distinct entities. You could write 3 as 2 and 2/2, but that's not usually done.
