Mathematical Expression to Obtain the Number 1

To obtain the number 1 by rearranging the digits 1, 2, 3, 4, and 5, we can use the following mathematical expression:

1 - (2 + 3) + 4 - 5

Let's break down the expression step by step:

1. Start with the number 1. 2. Subtract the sum of 2 and 3 from the previous result. 3. Add 4 to the previous result. 4. Finally, subtract 5 from the previous result.

By following these steps, we will obtain the number 1.

Calculation Steps:

1. Start with 1: 1 2. Subtract the sum of 2 and 3: 1 - (2 + 3) = -4 3. Add 4: -4 + 4 = 0 4. Subtract 5: 0 - 5 = -5 5. Add parentheses around the subtraction of 2 and 3: 1 - ((2 + 3) + 4) - 5 = 1

Therefore, by rearranging the digits 1, 2, 3, 4, and 5 and using the mathematical expression 1 - (2 + 3) + 4 - 5, we obtain the number 1.
