Fill in the fields. There is nothing to upload because there is nothing to send — the numbers you enter never leave this tab.
The arithmetic runs in your browser, on your own device, and the answer updates with every keystroke. Nothing is sent anywhere — so there is no record of what you earn, what you owe, or what you are thinking of buying.
