None. All counting numbers are even or odd.
All numbers are either odd or even, none are both, so less than 30 there are 29 counting numbers that are either odd or even but not both. (Assuming you mean starting to count with 1.)
The natural numbers are the counting numbers. Therefore, the natural numbers less than 31 are the numbers from 1 to 30.
its must be 10
To find the two-digit counting numbers less than 30, we consider the numbers from 10 to 29, which gives us 20 two-digit numbers. The multiples of 20 that are two-digit numbers are 20. Since 20 is already included in the count of two-digit numbers less than 30, the total remains 20. Therefore, there are 20 two-digit counting numbers that are either less than 30 or a multiple of 20.

1 and it is 2
1,2,3,4,5,6,7,8
The natural numbers are the counting numbers. Therefore, the natural numbers less than 31 are the numbers from 1 to 30.
its must be 10
3 is one example.
The natural numbers are the counting numbers Thus the set m of those counting numbers less than 5 is: m = {1, 2, 3, 4}
{3,6,9,12,15,18,21,24}
An infinite number of even numbers are less than 10.
counting numbers greater than 1but less than 10 = 2, 3, 4, 5, 6, 7, 9
