Method to use all the numbers in a string to equal other number

In summary, the method to use all the numbers in a string to equal another number involves converting the numbers into individual digits and using mathematical operations. It can be applied to any string of numbers and can produce accurate results if used correctly. The number of numbers needed in the string varies and there may be limitations for non-numeric characters, extremely large numbers, and complex mathematical equations.

I was recently given the challenge to take a string of numbers (ages) and + x - / to equal another number (age). As part of the challenge each number can only be used once and you must only use numbers here to do multiply, add to, subtract from or divide by.

NUMBERS
7 9 11 37 45 45 47 75
TARGET NUMBER
70

Im not looking as much for the answer, more if there is any efficent method to do this rather than guess and check

Do you have to use each number once, or can I omit some of them from the solution?
 

1. How does the method to use all the numbers in a string to equal another number work?

The method involves converting all the numbers in the string into individual digits and then using mathematical operations such as addition, subtraction, multiplication, or division to manipulate them in order to equal the desired number.

2. Can the method be used for any string of numbers?

Yes, the method can be applied to any string of numbers as long as they can be converted into individual digits and manipulated using mathematical operations.

3. Is the method reliable in producing accurate results?

The method is based on mathematical principles and can produce accurate results as long as the numbers and operations are used correctly.

4. How many numbers do I need in the string to equal another number using this method?

The number of numbers needed in the string depends on the numerical values and operations used. In some cases, it may be possible to use all the numbers in the string, while in others, only a subset of the numbers may be needed.

5. Are there any limitations to using this method?

The method may not work for strings that contain non-numeric characters or for extremely large numbers that may cause overflow in the mathematical operations. Additionally, the method may not be suitable for complex mathematical equations or problems that require specific mathematical functions.
