# Number product calculator

World's simplest number tool
Quickly calculate the product of numbers in your browser. To get a product, just enter your list of numbers in the input field, adjust the separator between the numbers in the options below, and this utility will multiply all these numbers together. Created by developers from team Browserling.
Number Extraction
Make the program extract all
numbers from any text data
automatically.
Configure the number delimiter
in the options manually.
Enter a character that separates
numbers. (By default a newline.)
What to do with zeros?
Skip all zeros in the list
so that the product
doesn't equal 0.
Running Product and Multipliers
Print partial products of the
multiplication progress.
Print the multipliers that
make up the product.

## What is a number product calculator?

This is an online browser-based utility for calculating the product of a bunch of numbers. You can input strictly numerical data or mixed textual data and obtain the result of all the numbers multiplied together as the output. The program has two modes of recognizing numbers in the input data. The first one is called "Smart Product" and it automatically identifies and extracts all numbers in the text. The "Custom Delimiter" mode allows you to manually configure the delimiter character for comma-separated, space-separated, newline-separated, or other number list formats. The numbers can be whole numbers and decimal numbers. If there is at least one zero among the factors, then the total product equals zero. To avoid such cases, we have a special option that skips zeros and displays the product of all other numbers. We also have a useful option that shows the running product of multiplying several numbers. If this option is enabled, then a partial product at each multiplication step is printed. To see the factors that contributed to a particular product, you can activate the "Display Product Multipliers" option, which will display all the multipliers of the product in parentheses. That's numberwang!

## Number product calculator examples

Product of Various Numbers
In this example, we multiply together 10 different numbers at once. There are integers, fractions, negative and positive values among them. Numbers are listed in a column and the new line character is used to separate them.
20 -6 45 0.2 50 66 0.03 -1.5 0.01 100

Find the Volume of a Cuboid
In this example, we calculate the volume of a rectangular cuboid by simply inputting the text with numeric data that describes it. The input consists of three numerical parameters: 12 (length), 20 (width), and 10 (height) and as we have enabled the "Smart Product" option, the utility automatically extracts these numbers from the text, multiplies them, and finds the cuboid's volume.
A rectangular cuboid has a length of 12 inches, a width of 20 inches, and a height of 10 inches.

Skip Zeros in the Product
This example calculates the product of 35 whole numbers. As this sequence contains many zeros, the multiplication should give a zero, but as we have enabled the "Skip Zeros" option, it finds the product of all numbers except zero: 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10 × 20 × 30 × 40 × 50 × 60 × 70 × 80 × 90.
1; 0; 2; 0; 3; 0; 4; 0; 5; 0; 6; 0; 7; 0; 8; 0; 9; 0; 10; 0; 20; 0; 30; 0; 40; 0; 50; 0; 60; 0; 70; 0; 80; 0; 90

Multiply Numbers Directly in Text
In this example, we find the running product for the solution of a mathematical problem that's written as text. As all the numbers that we need to multiply are present in the given text, we simply paste the entire text as the input and allow the program to automatically extract them and multiply them together. Additionally, we enable the "Display Product Multipliers" mode to see all the factors that are used at each multiplication step.
Math problem: How many ways are there to line up eight people for a photo shoot? Solution: To calculate this, we need to find the factorial of eight, which means multiplying 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8.
1 (1) 2 (1 × 2) 6 (1 × 2 × 3) 24 (1 × 2 × 3 × 4) 120 (1 × 2 × 3 × 4 × 5) 720 (1 × 2 × 3 × 4 × 5 × 6) 5040 (1 × 2 × 3 × 4 × 5 × 6 × 7) 40320 (1 × 2 × 3 × 4 × 5 × 6 × 7 × 8)
Required options

Total Running Product
This example activates the "Display Running Product" option and shows the multiplication process step by step. As we can see, the first three numbers (10, 20, 40) are positive and greater than zero, so their product increases at each stage (10, 10 × 20 = 200, 10 × 20 × 40 = 8000). The next number is negative and it turns the partial product negative (10 × 20 × 40 × (-80) = -640000). The sixth factor is zero and as we have deactivated the "Skip Zeros" option, the product becomes zero and stays zero till the end. It doesn't matter what numbers are next because once there is a zero, the total product is always 0.
10 20 40 -80 100 0 1 2 3
10 200 8000 -640000 -64000000 0 0 0 0
