Semaj & Jlah were playingthe card game - Jlah had a score of (-10) & Semaj took away one of her cards & the card was (-8) --- Jlah recalculated her score to be (-2) but Semaj disagreed & sais her score was (-18) --- Jlah said, "Removing a negative card is the same as adding the positive card. My score will go up. Negative 10 minus negative 8 is negative 2." Semaj said, " Removing a negative card means the same thing as subtracting a positve. So, negative 10 minus negative 8 is neagative 8 is neative 18." BASED on their disagreement, who, if anyone, is right? EXPLAIN anwser this ASAP pleasse
