Final answer:
The expression that shows the difference between 8 and 2 is 8 - 2, which equals 6. This subtraction operation is represented by option C) 8-2.
Step-by-step explanation:
The question asks for the expression that shows the difference between 8 and 2. To find the difference in mathematics, you subtract one number from another. The correct expression for the difference between 8 and 2 is 8 - 2, which equals 6. So the answer is option C) 8-2.
As an example, consider the subtraction of a positive number: 5 - (+3) = 5 - 3 = 2. Similarly, subtracting a negative number involves changing the subtraction to addition: 2 - (-6) = 2 + 6 = 8. This concept applies to any subtraction operation, and the original signs of the numbers are important in determining the final result.
