What is the law of blackjack game in junior high school mathematics?
As a poker intelligence game, we should also pay attention to skills in calculation. When calculating, we can't try different combinations of the four numbers on the card surface, let alone fiddle around. The following are some commonly used methods, which are easy to learn and master: 1. Use 3× 8 = 24 and 4× 6 = 24 to unlock the card. Then multiply 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, etc. 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 example, 4,5, j and k can form 1 1. The most widely used solutions are as follows: (We use A, B, C and D to represent 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) ÷. Such as (9+5-2) × 2 = 24, etc. ⑤ A× B+C-D is11× 3+L-10 = 24, etc. ⑤ (A-B) × C+D is (4-L) × 6+.
