Explanation:

For adding/subtracting integers, using the number line helps visualize moving positive/negative values to simplify. For multiplying/dividing, applying sign rules first streamlines calculating the final value.

Answer:

• One strategy I use for adding and subtracting integers is using a number line to track positive and negative movements, where adding a positive integer moves right and adding a negative (subtracting) moves left to simplify the expression.
• One strategy I use for multiplying and dividing integers is applying the sign rules first: same signs result in a positive product/quotient, different signs result in a negative product/quotient, then calculate the absolute value of the numbers to get the final simplified value.
