The rules of primary school mathematics blackjack poker game are as follows. First, the basic rule is to draw the remaining 52 cards from a deck. (If you practice for the first time, you can only use 40 cards of 1- 10. ) You can randomly draw 4 cards (called deck cards), and count the numbers on the deck cards as 24 by adding, subtracting, multiplying and dividing (brackets can be added). 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 (9-8÷8)×3, and so on. As a poker intelligence game, we should also pay attention to skills in calculation. When calculating, it is impossible for us to try different combinations of four numbers, let alone touch them together. Second, the skill 1 is solved by 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, etc. 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.
