Math Problem Statement

Use the digit cards to make the subtraction problem correct. Each card can only be used once.

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 A=48357A = 48357, and the lower row by B=1926B = 1926. The subtraction should result in C=46431C = 46431.

The subtraction can be set up as: 483571926=4643148357 - 1926 = 46431

Let's check if this subtraction is correct:

483571926=4643148357 - 1926 = 46431

Yes, this is correct.

Final Solution:

  • Upper number: 48357
  • Lower number: 1926
  • Result: 46431
