Number sum calculator tool What is a number sum calculator?
This is an online browser-based utility for calculating the sum of a bunch of numbers. You can enter numbers separated by a comma, space, or any other character, including the line break. The input sequence of values can contain positive and negative numbers, integers and fractions. Regardless of the input set, this tool finds the total sum. You can also activate the "Print Running Sum" option, which shows how the sum changes at each step when calculating the sum of multiple numbers. That's numberwang!

Sum of Integers and Decimals
In this example, we add together ninety different values – positive numbers, negative numbers, integers and decimal fractions. We set the input separator to a comma and after adding all of them together, we get 0 as output.
1, 2, 3, 4, 5, 6, 7, 8, 9, -1.1, -2.1, -3.1, -4.1, -5.1, -6.1, -7.1, -8.1, -9.1, 10, 20, 30, 40, 50, 60, 70, 80, 90, -10.2, -20.2, -30.2, -40.2, -50.2, -60.2, -70.2, -80.2, -90.2, 100, 200, 300, 400, 500, 600, 700, 800, 900, -100.3, -200.3, -300.3, -400.3, -500.3, -600.3, -700.3, -800.3, -900.3, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, -1000.4, -2000.4, -3000.4, -4000.4, -5000.4, -6000.4, -7000.4, -8000.4, -9000.4, 10001, 20001, 30001, 40001, 50001, 60001, 70001, 80001, 90001, -10000, -20000, -30000, -40000, -50000, -60000, -70000, -80000, -90000

Running Sum of Numbers
In this example, we calculate the sum of all ten digits and enable the option "Print Running Sum". We get the intermediate values of the sum in the process of addition. Thus, we have the following sequence in the output: 0, 1 (0 + 1), 3 (0 + 1 + 2), 6 (0 + 1 + 2 + 3), 10 (0 + 1 + 2 + 3 + 4), and so on.
0 1 2 3 4 5 6 7 8 9
