The steps of the game are: 1, four people play together, each draws 13 cards, and each person draws a card from his hand at any time.
2. Players can add, subtract, multiply and divide the numbers of these four cards, and they can also add brackets to make the result equal to 24.
Whoever lists the formula with the result of 24 first gets 1 point. If no one in the game can list it, no one can score. Put the card at the bottom.
3. Continue to follow steps 1 and 2 until all the 13 cards in everyone's hands are used up. The winner is the one who scores more points in the end. For example, if the four cards are Q, 10, Q, 1, then use12× (12-10 )×1= 24.
Therefore, if you want to win the game, you can't just rely on hard work. Even then, it will be slow. Therefore, skill is also very important. In other words, we must be very clear about how 24 is obtained from two numbers. The first case is multiplication, for example: 2× 12 = 24, 3× 8 = 24, 4× 6 = 24; The second case is addition and subtraction, such as: 16+8=24, 28-4=24, 32-8 = 24 ... so we turn the problem of four numbers into the problem of two numbers, and the calculation is much simpler.
