Answer:

Explanation:

I agree the wording is confusing, but I can give a brief summary of subtracting integers with different signs.

Subtracting integers:

1. Subtract the values

2. Take the sign of the number with the greatest absolute value


Ex:

-16+4

16-4=12
since the absolute value of -16 is greater the answer is negative

Answer=-12

Answer:

When adding integers with different signs, the rule of subtracting is used.

- This rule is used because the positive value increases the sum and the negative value decreases the sum.

- When the signs are different, we take the absolute values of each number.

- The answer will have the sign of the number that had the larger absolute value.

Now, let's solve the given problems step-by-step:

1. -12 + 3:

- Since the signs are different (negative and positive), we subtract the absolute values of the numbers: |-12| - |3|.

- |-12| equals 12 and |3| equals 3.

- So, we have 12 - 3.

- The answer will get the sign of the number that had the larger absolute value, which is -12.

- Therefore, -12 + 3 equals -9.

2. 16 + (-13):

- The signs are different (positive and negative), so we subtract the absolute values: |16| - |(-13)|.

- |16| equals 16 and |(-13)| equals 13.

- Therefore, we have 16 - 13.

- The answer will get the sign of the number that had the larger absolute value, which is 16.

- Hence, 16 + (-13) equals 3.

3. The sum of 44 and -89:

- The signs are different (positive and negative), so we subtract the absolute values: |44| - |(-89)|.

- |44| equals 44 and |(-89)| equals 89.

- Therefore, we have 44 - 89.

- The answer will get the sign of the number that had the larger absolute value, which is -89.

- Thus, the sum of 44 and -89 is -45.

4. The total amount of yards gained or lost during the possession:

- We need to add up the yard values: +3, -2, and +5.

- The positive values represent yards gained, and the negative values represent yards lost.

- Adding +3, -2, and +5 gives us a total of 6 yards gained.

- Therefore, the total amount of yards gained or lost during this possession is 6 yards.
