Once you've decided what number you want it to be at the end of the trick and typed it in. Here's the set up. First hit the plus key.
Then tap the 0 (zero) key.
Then click the (x) multiply key.
Then just close the app. When you want to perform the trick just open the calculator and you're ready to start adding the numbers they name and multiply them together.
After all the numbers they name are entered and multiplied together. When you hit the equals at the end it'll automatically show the number you entered before hand.
