Remember the game 24? You probably played it in middle school. You get
four numbers, and you have to use operations that make them equal 24.
Well, this is the toughest 24 problem I've ever seen. Solve it by
Sunday, October 3, and I'll bring you in a special treat. Here's a hint:
It involves fractions. Good luck! I got stuck on it for awhile. Using only the numbers 1, 3, 4, and 6, together with the operations +, −, ×, and ÷, and unlimited use of brackets, make the number 24. Each number must be used precisely once. Each operation may be used zero or more times. Decimal points are not allowed, nor is implicit use of base 10 by concatenating digits, as in 3 × (14 − 6). As an example, one way to make 25 is: 4 × (6 + 1) − 3. |
