This calculator uses "Faraday's Principle of Electromagnetic Energy" to operate. A magnet moving by a copper wire produces an electric current that powers the calculator, no batteries required! Shake it left to right non-stop 20-25 times, and enough electricity is generated to operate the calculator for 10 minutes. When the digits on the LCD screen dim, just shake it a few more times to recharge, your calculations won't be lost.
