How many three digits counting numbers are multiple of 2?
Three-digit counting numbers range from 100 to 999. To find how many of these are multiples of 2, we note that the smallest three-digit multiple of 2 is 100, and the largest is 998. The sequence of three-digit multiples of 2 can be represented as 100, 102, 104, ..., 998, which forms an arithmetic sequence with a common difference of 2. The total number of terms in this sequence can be calculated as ((998 - 100) / 2 + 1), resulting in 450 three-digit counting numbers that are multiples of 2.
How many four digit counting numbers are not multiple of 5?
There are 7200 such numbers.
How many three digit counting numbers are multiples of 2 but not of 55?
There are 898 three-digit even numbers. Nine of them are multiples of 55. That leaves 889 * * * * * There are 450 three-digit even numbers and 17 of them are multiples of 55. So that leaves 433.
How many two-digit counting numbers are less than 30 or a multiple of 20?
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.
What is the difference between integers and counting numbers?
The counting numbers are {1, 2, 3, ...}. The integers are the counting numbers, their opposites (-1, -2, ...) and zero. So they are {..., -2, -1, 0, 1, 2, ...}.

How many two-digit counting numbers are greater than 70 or a multiple of ten?
- There are an infinite number of "counting numbers" that are greater than 70. - There are also an infinite number of "counting number" that are multiples of 10. So.... since you used an "OR" statement, this mean how many number are true for both statements above. That would be: AN INFINITE NUMBER of counting numbers. In fact, if you had said "AND", it still would be an infinite number: 80, 90, 100, ... and so on FOREVER. * * * * * The above answer has interpreted the questions as "two-digit counting numbers greater than 70" OR "a multiple of ten". Apart from the fact that there are not an infinite number of two-digit counting numbers greater than 70, the answer would be correct. But the answer could be interpreted as "two digit counting numbers" that are "greater than 70" OR "a multiple of ten". In that case, the first set is {71, 72, ... 99} and the second is {10, 20, 30, ... 90} with an intersection set consisting of {80 and 90} So there are 29 + 9 - 2 = 36 such number.

Is The counting numbers are also known as the natural numbers?
yes! just think of it this way: when someone tells you start counting, you "naturally" start with 1, 2, 3, 4, 5,...and so on. that's helps you remember the words natural numbers, because you "naturally" start counting at 1. it's the same with counting numbers. if someone told you to start counting, you would start with 1, 2, 3, 4, 5,...and so on. this helps you remember counting numbers, because you start "counting" with 1. get it??! =D
