Frequently Asked Questions
What is a running product?
It is the product built up step by step. Each line multiplies the product so far by the next number, so you can see how it grows.
What happens if one number is zero?
The running product becomes zero from that point on, since multiplying by zero gives zero.
Does it handle decimals and negatives?
Yes. Numbers are multiplied as values, and a negative flips the sign of the running product.
What is the last line?
The last line is the product of all the numbers you entered.
Is my data uploaded?
No. The calculation runs in your browser and your numbers never leave the tab.
