Question 2: When adding rational numbers, if the signs are the same, then:
- The correct response is: Add the numbers. Keep the sign.
This means that if both numbers are positive, you add them and the result is positive. If both numbers are negative, you also add their absolute values and keep the negative sign.
Question 3: When adding rational numbers, if the signs are different, then:
- The correct response is: Subtract the numbers. Take the sign of the larger number.
This means that you subtract the smaller absolute value from the larger absolute value and take the sign of the number with the larger absolute value.
