Old Calculator Trick

Published by simon on August 24, 2010

Here’s an old trick with a calculator that my dad showed me when i was small. Works with any digital LCD calculator (not your handphone one, though).

142 (key in ’142′) Americans are battling 154 (then key in ’154′) Arabs over 69 (and then key in ’69′) Gallons of oil times 5 (multiply by 5) trucks that are carrying it. What oil is it??

Press equals for the answer and turn the calculator upside down for the answer.

Haha. The things we amused ourselves with those days before the Internet…
