Integer adder
World's simplest integer tool
This browser-based utility adds all the given integers and prints their sum in the output. You can immediately calculate the total of multiple integers or enable partial sum mode and follow the summation process step by step. Each integer should be put on its own line but you can customize the integer separator in the options. Created by math nerds from team Browserling.

What is a integer adder?
learn more about this tool
With this online application, you can calculate the sum of integers. There's no limit to how many values you can sum up at once. It works with tens, hundreds, and even thousands of values. There's also no limit to the integer length. They can be very, very large up to one million digits. By default, values should be entered in a vertical sequence with one value on each line. If your sequence of integers has a different format, then just enter the separator that the list is using in the integer separator option. There is also another useful option. The "Show Partial Sums" option shows the partial sum as the total sum is computed. The partial sum shows the sum up to the current integer, which includes all preceding integers. For example, if you have a list of values 5, 10, 20, 30, then with the partial sums option active, you'll get 5, 15 (5 + 10), 35 (15 + 20), 65 (35 + 30). Integerabulous!
Integer adder examples
Click to useSum of 1 to 100
In this example, we find the total of adding the first one hundred natural numbers. We paste a sequence of comma-separated integers from 1 to 100 in the input, and the webapp adds them in this way: 1 + 2 + 3 + 4 + … + 100. In the output, it displays the sum, which is equal to 5050. We also set the separator to the comma symbol to correctly split the sequence into individual integers.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100

Required options
Enter symbol that separates
input integers.
Output the running sum,
adding the current integer
to the preceding integers.
Alternating Signs Sum
This example sums a list of eight integers with alternating signs. The first integer is positive, the second is negative, the third is positive, and so on. Each list item is written on a separate line, so we use the character "\n" that denotes a newline in the list item delimiter option. Since the absolute value of negative integers is greater than the absolute value of positive integers, we get a negative sum equal to -10000.

-10000
Required options
Enter symbol that separates
input integers.
Output the running sum,
adding the current integer
to the preceding integers.
Integer Partial Sum
In this example, we enable the "Show Partial Sums" option to see how the sum changes as every next integer is added to the previous ones. Initially, the partial sum value is equal to the first integer and is equal to 100. The second partial sum is calculated by adding the second integer to the first partial sum so now it's 100 + (-45) = 55. Then the third integer is added to the previous partial sum and we get 55 + (-30) = 25. This continues until all integers are added. Each partial result is displayed on a new line, and the last value is the total sum of all integers.
