Usually, playing cards are used to play games. There are 52 cards left in a deck (40 cards 1 ~ 10 can be used for initial training), and 4 cards are randomly selected (called deck cards). Add, subtract, multiply and divide (brackets can be added) to calculate the number on the deck as 24. Each card can only be used once. If the cards drawn are 3, 8, 8 and 9, then the formula is (9-8) × 8× 3 or 3× 8 ÷ (9-8) or (9-8 ÷ 8 )× 3, and so on.
As a poker intelligence game, Count 24 points should also pay attention to skills in calculation. When calculating, it is impossible for us to try different combinations of the four numbers on the card surface, let alone touch them together. Here are two common methods that are easy to learn:
1. Solve with 3×8=24 and 4×6=24.
Try to sum the four numbers on the card face into 3 and 8, 4 and 6, and then multiply them to solve. For example, 3,3,6 and 10 can form (10-6÷3)×3=24 or (10-3-3)×6=24. For example, 2, 3, 3 and 7 can form (7+3-2)×3=24 and so on. Practice has proved that this method has the highest utilization rate and hit rate.
2. Use the operational characteristics of 0, 1 1 to solve it.
For example, 3, 4, 4 and 8 can form 3× 8+4-4 = 24. For another example, 4,5, j and k can form11× (5-4)+13 = 24 and so on.
