The question shown in the image relates to understanding the concept of adding and subtracting negative and positive numbers. Let's break it down:

1. Question 1a: The correct statement here should be:

   • Subtracting a negative is the same as adding a positive.

   In mathematical terms, if you subtract a negative number, it becomes positive. For example: $5 - (-3) = 5 + 3 = 8$

   The selected option in the image (marked with red) says, "Subtracting a negative is the same as adding a negative," which is incorrect.

2. Question 1b: Likely part of 1a's completion. It appears to be asking for an explanation of how you know the correct answer based on the number line or workbook exercises.

3. Question 1c: This section involves entering a numerical answer related to the workbook exercise on page 177.

Would you like more help solving this problem in detail, or further assistance with the number line example?

Here are some follow-up questions to help deepen your understanding:

1. What happens when you subtract a positive number?
2. Can you give an example of subtracting a negative number using a number line?
3. Why is subtracting a negative number the same as adding a positive?
4. What happens when you subtract two negative numbers?
5. How would you explain adding and subtracting negatives to someone else?

Tip: When subtracting any number, think of it as moving to the left on a number line; if subtracting a negative, it means moving to the right.
