How it works
The sum is every number in the list added together. A negative number is subtracted, so a minus sign works as you would expect.
Totals such as expenses or hours often come from adding a column like this. Check the count too, so you know every line was included.
Worked example
Your 4 numbers add up to 55.25.
Questions
Can I include negative numbers?
Yes. Type a minus sign in front of the number, and it is subtracted from the total.
What should I leave out of the list?
Leave out words and units, and keep just the numbers. Then the count matches the entries you meant to add.
Is there a limit to how many numbers I can add?
There is no fixed limit in this tool, but very long lists are easier to check in a spreadsheet.
