## 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 the numbers separated by a comma, space, or any other character, including the line break. You can also simply paste a fragment of textual data that contains numerical values that you want to sum up and the utility will extract them and find their sum. For example, if the input data is a sentence "20 apples and 30 pears", then you can enable the "Smart Sum" number extraction mode, and the program will automatically find the numbers 20 and 30 in the sentence, and calculate their sum: 20 + 30 = 50. On the other hand, if you input a well-formatted numerical list like "1, 2, 3, 4", then you can switch to the "Number Delimiter" mode, configure the number delimiter (in this case, it's a comma followed by a space ", "), and get the sum of 1 + 2 + 3 + 4 = 10 as the output. The input sequence of values may contain positive and negative numbers, integers, and fractions. Regardless of the input set of numbers, this tool always finds the total sum. You can also activate the "Print Running Sum" option, which shows how the sum changes with each next addend when calculating the sum of multiple numbers. Additionally, you can enable the "Show Sum Details" option to display all the addends that make up the current sum at each stage of the calculation. That's numberwang!

Count Trees in the Park
In this example, we calculate the total number of trees in the central park of our city by pasting the entire text report into the input area of the tool. To avoid doing manual cleanup work of the text, we use the "Smart Sum" option, which automatically finds and extracts all the numbers in the text, and then calculates their sum.
This year gardeners have planted 20 red maples, 35 sweetgum, 13 quaking aspen, and 7 white oaks in the central park of the city.

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.

Find the Total of a Receipt
In this example, by using the smart sum algorithm, we calculate the total cost of purchases in a grocery store. The smart sum algorithm scans all the characters in the receipt and extracts only the numerical values from it. To verify that the sum was calculated correctly, we display the running total of all prices together with the addends.
Apples \$4.50 Milk \$3.00 Bread \$2.50 Eggs \$2.99 Chicken \$6.99 Rice \$1.99 Tomatoes \$1.25 Pasta \$3.98 Cheese \$2.75

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.
