How it works
Online Calculator is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.
Adding up a list
Type the whole list with plus signs, such as 12.50 + 8.99 + 23 + 4.75, and press Enter. The history keeps the sum and the full line, so you can check what you typed.
