Integer Operations on a Number Line

Mason and Olivia are collecting stamps. Mason says, "I have 5 stamps," and Olivia adds, "I have 7 more stamps." How many stamps do they have together?

Answer explanation

To find the sum of 5 and 7, simply add the two numbers: 5 + 7 = 12. Therefore, the correct answer is 12.

Ethan had 15 candies and he gave 8 to his friend Harper. How many candies does Ethan have left?

Answer explanation

To find the result of 15 - 8, subtract 8 from 15. This gives 7, which is the correct answer. The other options (8, 6, and 5) do not result from this subtraction.

Answer explanation

To solve -4 + (-3), add the two negative numbers: -4 + -3 = -7. Therefore, the correct answer is -7.

Lily and Mason are playing a game of integers. Lily says, "I have -10 points, but I can remove -5 points from my score!" What will Lily's new score be?

Answer explanation

To solve -10 - (-5), we rewrite it as -10 + 5. This simplifies to -5. Therefore, the correct answer is -5.

Answer explanation

To solve -6 + 9, add 9 to -6. This results in 3, which is the correct answer. The other options do not match this calculation.

William and Liam are playing a number game. William says, "I have 8 apples, but I lost 13 of them in a magic trick!" How many apples does William have now?

Answer explanation

To solve 8 - 13, subtract 13 from 8. Since 8 is less than 13, the result is negative: 8 - 13 = -5. Therefore, the correct answer is -5.

Mia and Daniel are playing a game of numbers. Mia says, "I have -7 apples and I give away 4 more." How many apples does Mia have now?

Answer explanation

To solve -7 - 4, subtract 4 from -7. This results in -11, as moving left on the number line from -7 by 4 units leads to -11. Therefore, the correct answer is -11.

Answer explanation

To solve -2 + 6, add 6 to -2. This results in 4, which is the correct answer. Therefore, the answer is \(4\).

Noah and Mia are playing a number game. Noah says, "I have 3 apples, but I lost 8 of them in a magic trick!" How many apples does Noah have now?

Answer explanation

To solve 3 + (-8), we subtract 8 from 3. This gives us 3 - 8 = -5. Therefore, the correct answer is -5.

Aiden and Harper are playing a number game. Aiden says, "I have -9 apples, and I give away -2 apples." How many apples does Aiden have now?
