The formula for the first n positive numbers is n x (n+1)/2, so for n=11 the sum is 11 x 12 /2 = 66
The sum of the first three even positive integers is 2 + 4 + 6 = 12.

The first ten positive numbers total 55.
To find the average of integers, add them all together then divide the total by the number of integers.

They total 650. * * * * * It is 2550.
The positive integers up to 4 are: 1, 2, 3, and 4. This is a total of four positive integers.
The sum of the first three even positive integers is 2 + 4 + 6 = 12.

900 This explains it. A positive integer is a palindrome if it reads the same forward and backwards such as 1287821 and 4554. Determine the number of 5-digit positive integers which are NOT palindromes. We start by counting the total number of 5 digit positive integers. The first digit is between 1 and 9, so we have 9 choices. Each of the other 4 digits can be anything at all (10 choices for each). This gives us 9(10)4 = 90000 five-digit positive integers. Now we need to count the number of 5 digit palindromes. Again, we have 9 choices for the first digit and 10 choices for each of the next two. The tens and units digits however are fixed by our choices so far. Therefore, there are only 900 five-digit palindromes. Therefore, the total number of five-digit positive integers which are not palindromes is 90000-900 = 89100.
Combine them together, using the rules of priority (PEMDAS or BIDMAS).
The first ten positive numbers total 55.
If a number is at least 5, and ends in "5" or "0", then it is divisible by 5. To further elaborate, If we are speaking of all numbers, the answer is an infinite number. If we limit it to positive integers, the answer is 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0. Eleven total since 0 is a positive number.
There are one thousand. Starting at 2000 and going to 2999
To find the total number of integers between 100 and 300 that are divisible by 3, we first determine the smallest and largest integers in this range that are divisible by 3. The smallest integer divisible by 3 is 102, and the largest is 297. To find the total number of integers between 102 and 297 that are divisible by 3, we calculate (297-102)/3 + 1, which equals 66. Therefore, there are 66 integers between 100 and 300 that are divisible by 3.
To find the average of integers, add them all together then divide the total by the number of integers.
To find the number of three-digit positive integers with digits whose product is 24, we can break down 24 into its prime factors: 2 x 2 x 2 x 3. The possible combinations for the three digits are (2, 2, 6), (2, 3, 4), and (2, 4, 3). These can be arranged in 3! ways each, giving a total of 3 x 3! = 18 three-digit positive integers.
