Answer 1

Пошаговое объяснение:

(7*9)+(6*8)-(5*2)-1*(4-3)

Answer 2

Arithmetic operations are mathematical calculations that involve the four basic operations: addition, subtraction, multiplication, and division. In order to determine which arithmetic operations are needed to make the sum of the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 equal to 1000, we need to analyze and manipulate the numbers.

One approach to solving this problem is to examine the given numbers and look for patterns or relationships that can be used to find a solution. In this case, adding the numbers 1 to 9 together equals 45 (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45), which is far from 1000. Therefore, additional arithmetic operations need to be performed.

To find the missing arithmetic operation, we need to determine the difference between the sum of the numbers 1 to 9 and 1000. The difference is 1000 - 45 = 955. This means that we need to find a way to add 955 to the sum of 1 to 9 using arithmetic operations.

One possible solution is to concatenate the numbers 1 to 9 in a specific order and perform arithmetic operations. For example, if we concatenate the numbers in descending order (9, 8, 7, 6, 5, 4, 3, 2, 1), we can add them together using addition and multiplication to get the desired result:

9 + 8 x 7 + 6 x 5 x 4 - 3 + 2 - 1 = 1000

In this case, the addition of 9, the multiplication of 8 and 7, the multiplication of 6, 5, and 4, and the subtraction and addition of 3, 2, and 1 result in a sum of 1000. This is just one possible solution, and there may be other ways to achieve the same result using different arithmetic operations.

In conclusion, finding the arithmetic operations to make the sum of the numbers 1 to 9 equal to 1000 requires analyzing the numbers and looking for patterns or relationships. By manipulating the numbers using arithmetic operations, such as addition, subtraction, multiplication, and division, it is possible to find a solution. In this case, concatenating the numbers in a specific order and performing arithmetic operations resulted in a sum of 1000.
