QuickBooks accounting software has a built-in adding machine to simplify the entry of checks and credit card statements that require various calculations.
To access this built-in tool (available in all version of QuickBooks at least back to 2004), simply tap the = sign on your keyboard while sitting in any QuickBooks field where you would enter a number (i.e. check amount, invoice total, etc.). You will get a screen that looks like this:
Since the cursor appears AFTER the zeros, you'll want to get in the habit of hitting your backspace key a couple of times to remove the 0.00 that appears (I wish QuickBooks would fix that!!). Once you do that, type in your number, and use +, -, * or / for your data entry needs.
QuickBooks running slow or does it take forever to run a report? You may need QuickBooks Enterprise software - same easy-to-use screens you are used to, but much more horsepower to make things run faster!
