7 7 8 8 how to count 24 points

I can't figure it out, but I can refer to you.

1 Solve with 6 24.

Find a way to make up 3 and 6 from the four numbers on the board, and then multiply them to solve. For example, it can be composed of (10-6, 3), 3, 24, etc. For example, it can be composed of (7, 3-2), 3, 24, etc.

Practice has proved that this method is the method with the highest utilization rate and the highest hit rate.

2 Solve using the arithmetic characteristics of .

For example, it can be composed of 3, 8, 4, 4, 24, etc. For example, j, k can be composed of 11 (5-4) 13 24 and so on.

3 Among the solved decks, the following six solutions are most widely used: (we use A, B, C, D to represent the four numbers on the board).

a—b）×（c＋d）

Such as (10-4) (2, 2), 24, etc.

a＋b）÷c×d

Such as (10, 2), 2, 4, 24, etc.

a－b÷c）×d

Such as (3-2, 2), 12, 24, etc.

a＋b－c）×d

Such as (9, 5—2), 2, 24, etc.

a×b＋c—d

Such as 11 3 l—10 24 and so on.

a－b）×c＋d

Such as (4—l) 6, 6, 24, etc.

When playing, students may wish to give it a try according to the above methods.

It should be noted that according to the accurate calculation of the computer, a deck of cards (52 cards), there can be 1820 different combinations of 4 cards drawn at random, of which 458 cards can not be counted as 24 points, such as A, A, A, 5.

It is not difficult to see that the "24 Points of Clever Calculation" can greatly mobilize the coordination activities of the eyes, brain, hands, mouth and ears, which is very helpful for cultivating our quick mental arithmetic ability and reaction ability.

Students, you should also try "24 points", I believe you will like it quickly.

No, if you have any problems such as 24 points in the future, you can calculate on the ** I provided, it must be the most standardized!!

There is no solution to this problem, and you can only use addition, subtraction, multiplication, division, and parentheses to calculate 24, and nothing else can be.

8 to the third power + 8 + 7 + 7 = 24

Or there's no solution.

You can't count 24 points by addition, subtraction, multiplication, and division.

24 game rules: take a deck of cards, draw the queen (you can also take the king of j q k for the first practice), and leave 1 10 these 40 cards (the following replace a with 1). Draw any 4 cards (called a deck) and count the number on the board as 24 with addition, subtraction, multiplication, and division (parentheses, and advanced players can also use multiplication and factorial operations).

Each card must be used and can only be used once. If the card drawn is , then the equation is (9-8) 8 3=24.

Arithmetic skills. For example, it can be calculated as 4x6+8-8=24. Calculated using 2x x x6=24. For example, find a way to combine 4 numbers into any of the above three groups, (7+3-2)x3=24.

Use 3x x6=24 to solve, make up 3 and 8, 4 and 6, and multiply them to solve.

Summary. The first method: (7-7+8)*root number 9=24 This method maintains the order of the numbers in the question.

Step-by-step calculation: 7-7+8=8, root number 9=3, 8*3=24 Second method: (7-root number under (7+9)))*8=24 step-by-step calculation:

7 + 9 = 16, root number 16 = 4, 7-4 = 3, 3 * 8 = 24 of course is the first method is relatively simple.

Calculate 24 points.

Hello, glad to answer for you. 7 7 8 9=24 ( 9 represents the arithmetic square root of 9, which is equal to 3. ）

The first method: (7-7+8)*root number 9=24 This method maintains the order of the numbers in the question. Step-by-step calculation:

7-7+8=8, root number 9=3, 8*3=24 The second method: (7-under the root number (7+9))*8=24 step-by-step calculation: 7+9=16, root number 16=4, 7-4=3, 3*8=24 Of course, the first method is relatively simple.

You can't count 24 points by addition, subtraction, multiplication, and division. 24 game rules: take a deck of cards, draw the queen (you can also take the king of j q k for the first practice), and leave 1 10 these 40 cards (the following replace a with 1).

Draw any 4 cards (called a deck) and count the number on the board as 24 with addition, subtraction, multiplication, and division (parentheses can be added, and advanced players can also use the multiplier and factorial fortune to argue and calculate). Each card must be used and can only be used once. If the card drawn is , then the equation is (9-8) 8 3=24.

Arithmetic skills. For example, it can be calculated as 4x6+8-8=24. Calculated using 2x x x6=24.

For example, Yu Huai, find a way to combine 4 numbers into any of the above three groups, (7+3-2)x3=24. Use 3x x6=24 to solve, and find a way to make 3 and 8, 4 and 6, and then multiply them to solve.

7 plus 8 plus 8 plus (8 to the power of 0).

7 plus 8 plus 8 plus 1

One, forty-eight divided by two.

2. The 12 multiplication postures are blind to two.

Three, eight divided by one-third.

and jujube 8 ((7-5) 6) = 24

Four, eight times three.

8*(6 (7-5)) = 24

Five, six divided by a quarter.

Six, six times four.

There are many algorithms that have been scattered, such as:

3x（7-6）x8=24

3x8÷（7-6）=24

6x(3+(Hesun 8-7))=24

Two Kai large species algorithm:

3 8 (7-6) = 24

It's very simple, if you want to add four numbers, it's 24, 3+6+8+7=24
