Bryan and Jeanette were playing the Integer Card Game like the one you played in class. They were practicing adding and subtracting integers. Jeanette had a score of −10. Bryan took away one of Jeanette’s cards. He showed it to her. It was a −8. Jeanette recalculated her score to be −2, but Bryan disagreed. He said that her score should be −18 instead. Read their conversation, and answer the question below.
“No, Jeanette, removing a negative card means the same thing as subtracting a positive. So, negative 10 minus negative 8 is negative 18.”
“It does not! Removing a negative card is the same as adding the same positive card. My score will go up. Negative 10 minus negative 8 is negative 2.”
Based on their disagreement, who, if anyone, is right? Explain
