24 point calculator
24 points is a puzzle game. 24 points is a mathematical game in which 4 integers (usually positive integers) are added, subtracted, multiplied, divided and bracketed so that the final calculation result is 24. 24 points can test people's intelligence and mathematics. sensitivity, it can improve people's mental arithmetic skills in games.
blackjack is usually played with playing cards. after the big and small queens are drawn from a deck of cards, there are still 52 cards left (if you are just practicing, you can only use 40 cards from 1 to 10). 4 cards are randomly drawn (called deck), use addition, subtraction, multiplication, and division (parentheses can be added) to count the number on the card to 24. each card must only be used once. if the drawn cards are 3, 8, 8, 9, then the calculation formula is (9-8) × 8 × 3 or 3 × 8÷ (9-8) or (9-8÷ 8)×3 etc.
game tips
"counting 24 points" is a poker intelligence game, so you should pay attention to the technical issues in calculation. for example, when calculating, you cannot try different combinations of the four numbers on the card, let alone make them randomly. here are some commonly used methods that are easy to learn and master:
1. use 3×8=24, 4×6=24, 12×2=24 to solve.
find a way to combine the four numbers on the card into 3 and 8, 4 and 6, 12 and 2, and then multiply them to solve the problem. for example, 3, 3, 6, and 10 can form (10-6÷3)×3=24 or (10-3-3)×6=24. another example is that 2, 3, 3, and 7 can form (7+3-2)×3=24, etc. practice has proven that this method is the one with the highest utilization rate and highest hit rate.
2. use the operation characteristics of 0 and 1 to solve the problem.
for example, 3, 4, 4, and 8 can form 3×8+4-4=24, etc. another example is that 4, 5, j, and k can form 11×(5-4)+13=24, etc.
