Can YOU solve this fiendishly difficult math problem? 95% of MIT students CANNOT and only 10% of Stanford students CAN! Here it is: Can you make the number 24 from using 3, 3, 7, 7? And here are the rules: you have to use ALL the numbers but once only. You can use any of the standard four operations ± ÷ × as many times as you like – no powers though.
Solution
(3/7+3)*7 = 24
This was actually the basis of a game “24” that began in Shanghai in the early 1960s and became very popular in the 1990s to the extent that it became a game show. Many Chinese still play this game and that may, in part, explain why they are pretty fast with their mathematical calculations.
