Magic Box ∆

By Appibia

Open iTunes to buy and download apps.


Think you’ve got math figured out? Think again. Choose a two-digit number, perform a few simple operations, and be amazed when the Magic Box ∆ guesses what’s going on in your head. Abracadabra Einstein!


1. Think of a two-digit number.
2. Subtract the sum of the two digits from the number (for example, subtract 3 and 2 from 32 to get a difference of 27).
3. Find the difference (in this example, 27) and its corresponding symbol in the table.
4. Remember the symbol.
5. Click on the Magic Box ∆ and see what happens!
