Math Problem Statement
Solution
The task in the image is to arrange the given digit cards to complete a subtraction problem, with the condition that each digit card can only be used once.
We are given:
- The upper row of the subtraction problem:
4 8 3 5 7
- The lower row of the subtraction problem:
1 9 2 6
- The result of the subtraction:
4 6 4 3 1
Let's work through it:
We need to perform the subtraction of a five-digit number (formed from the upper row) minus a four-digit number (formed from the lower row) to get the five-digit result.
Let the upper row be represented by , and the lower row by . The subtraction should result in .
The subtraction can be set up as:
Let's check if this subtraction is correct:
Yes, this is correct.
Final Solution:
- Upper number: 48357
- Lower number: 1926
- Result: 46431
