Math Puzzle Solved To Turn On Lamp

Imagine a world where turning on something as ordinary as a light required you to use your brains as though you were solving tough puzzles. Enter this math-based lamp concept by Mingyu Jeung – you will need to get the answer to a randomly generated math problem correctly before the lamp can be turned on. Good thing it is set on a chalkboard for those who can’t juggle imaginary numbers in their heads. Chances are, there will be folks who decide to place a calculator nearby just in case their mental faculties fail them at that very moment. This concept won’t take off though, since we want our light instantly, instead of cracking our brains after a long day at the office.
