In each round of TwentyFour, you are given four random numbers between 1 and 9. Your goal is to use addition, subtraction, multiplication, or division to combine all of those numbers into an expression that results in 24. For example, suppose you got the numbers 8, 9, 2, and 5. The simplest solution is to add all the numbers together. But you can also go another way: start with 5 – 2 = 3, followed by 9 / 3 = 3, and finally 8 x 3 = 24. Here is another example: 2, 4, 6, and 3. One of the answers is 4 x 6 x (3 – 2). Can you spot another one?:)
