    One thought on “How to calculate at 24 o'clock?”
    1. At 24 o'clock, it is a puzzle game of chess and cards. The four digital operations are required to be equal to twenty -four. Let's play together! This game is easier to play with poker cards. Take a pair of cards and remove the queen of the size (you can also take the j/Q/K/size king), and the remaining 40 cards are left (1 with 1 instead of A). Exclude 4 cards (referred to as card groups) at will, use, subtract, multiply, and divide (can add brackets, senior players can also use multiplication and step computing) to count the number of cards on the card. Each card must be used and only once. If the drawn is 3, 8, 8, and 9, then the calculation is (9-8) × 8 × 3 = 24.

      game steps
      1. Use 3 × 8 = 24, 4 × 6 = 24, 12 × 2 = 24 Solve.
      n Numbers find a way to make up for 3 and 8, 4, and 6, and then multiply to solve. For example, 3, 3, 6, 10 can be composed of (10-6 ÷ 3) × 3 = 24, etc. Can compose (7 3-2) × 3 = 24, etc. Practice has proved that this method is a method with the largest utilization rate and the highest hit rate.

      2. Use the computing characteristics of 0 and 11 Solve.

      Such as 3, 4, 4, 8 to form 3 × 8 4-4 = 24, etc., such as 4, 5, J, K can form 11 × (5-4) 13 = 24 et al.

      3. Among the solved card groups, the most widely used is the following six solutions: (we use A, B, C, and D to indicate the four numbers on the card surface. )

      ① (A-B) × (C D) such as (10-4) × (2 2) = 24, etc.. ② (a b) ÷ c × d as (10 2) ÷ 2 × 4 = 24 et al.. ③ (A-B ÷ C) × D such as (3-2) × 12 = 24 et al.. ④ (a b-c) × d, such as (9 5-2) × 2 = 24 Waiting. × B C-D such as 11 × 3 L-10 = 24, etc..

      ⑥ (A-B) × C D such as (4-l) × 6 6 = 24, etc. During the game, students may wish to try it in accordance with the above methods.

      It what needs to be explained is that in the computer accurately calculated, the random 4 1-13 integer (duplicate) can be counted as 24 The probability of about 74.835%.

      "Calculating 24 points" can greatly mobilize the coordination activities of the eyes, brain, hands, mouth, and ears. It is very helpful and the reaction ability is very helpful.
