Add the same fixed number to every value in a list at once.
How It Works
How Add a Number to a List Calculator Works
The value you enter is added individually to each number in your list, producing a new list of the same length shifted up (or down, if the number is negative) by exactly that amount.
FAQ
Frequently Asked Questions
Can I use a negative number to subtract instead?
Yes — entering a negative value subtracts that amount from every item in the list instead of adding to it.
What's a practical use for this?
It's handy for quickly adjusting a whole dataset by a constant offset — for example, applying a flat curve to a list of test scores, or converting a list of relative values to absolute ones by adding a baseline.
