Screen Tape Adding Machine

This works like an old paper tape adding machine, except that the tape is on the computer screen, not on paper. To add a column of numbers, enter your first number in the top input box, and press the keyboard [Enter] key. A second input box will appear below the top input box.

Enter your second number in the second input box and press the [Enter] key. A third input box will appear below the second input box, and the total of the first two numbers will appear in the Total: box. Continue entering numbers, the total will appear in the Total: box.
