There's a trick to this one. Let 1 + 2 + ... + 500 be the sum of all integers 1 to 500, called X
Now, imagine we want to add the sum the integers from 1 to 500 and to the sum of the integers from 1 to 500. This would give us 2*X
we can write it as
1 + 2 + ... + 500
+
1 + 2 + ... + 500
But that's not particularly useful. What if we look at it as:
1 + 2 + ... + 499 + 500
+
500 + 499 + ... + 2 + 1
adding the numbers that are directly on top of each other, we get
500 + 1 = 501, 499 + 2 = 501... 1 + 500 = 501
Thus every term is 501, and we have 500 terms. So, we have 501*500 = 2X
Thus X, the sum from 1 to 500, is (500*501)/2 = 125,250

What is the sum of all even integers from 2 to 500 inclusive?
The formula n*(n+1) is used to find the sum of n positive integers. Th sum of positive integers up to 500 can be calculated as 250*251=62,750.
If you add all the numbers from 1-500 together what is it?
-499
What is the sum of the first 500 numbers?
The sum of the first 500 positive integers is: 1 + 2 + 3 + ... + 498 + 499 + 500 = 125250
What are the multiples of the 1 from 1 to 200?
All integers from 1 to 200.
The counting numbers are also known as the whole numbers?
This may or may not be true. The set of "counting numbers" may either be defined as all positive integers (1, 2, 3, 4...) or as all non-negative integers (0, 1, 2, 3, 4...). Similarly, the set of "whole numbers" may be defined as all positive integers, all non-negative integers, or as all integers (...-3, -2, -1, 0, 1, 2, 3...). It all depends on the definition given for each term.
Is 95 the sum of integers between 1 and 500?

How do you add and subbtract positive and negative integers?
When adding negative integers, you subtract. (2+-1=1) When subtracting negative integers, you add. (2--3=5)
What is the sum of the integers from 5 to 500?
The formula to sum a series of numbers is: sum = 1/2 x number_of_numbers x (first_number + last_number) So to sum the integers 5 to 500: From 5 to 500 there are 500 - 5 + 1 = 496 integers, so sum = 1/2 x 496 x (5 + 500) = 125240
If you add all the numbers from 1-500 together what is it?
-499
How any integers from 1 to 500 are divisible by 7?
To find the number of integers from 1 to 500 that are divisible by 7, we need to determine the number of multiples of 7 within this range. The first multiple of 7 in this range is 7, and the last multiple is 497. To find the count, we divide the last multiple by 7 and subtract the first multiple divided by 7, then add 1 (to include the first multiple). So, 497/7 - 7/7 + 1 = 71 - 1 + 1 = 71. Therefore, there are 71 integers from 1 to 500 that are divisible by 7.
What is the sum of all integers from 1 to 100?
It's easy to work it out yourself.... Multiply 100 by 49, add 50, add 100 - and you have your answer !
