Final answer:
Malik lost a total of 21 points after his first two turns in the game, by losing 16 points on the first turn and 5 points on the second turn.
Step-by-step explanation:
The student, Malik, is playing a game and needs to calculate his score after the first two turns. To find this, we can use the basic principles of arithmetic, specifically addition and subtraction. On his first turn, he loses 16 points, which we can represent as -16. On his second turn, he loses an additional 5 points, represented as -5. To find the total score change after these turns, we simply add the two numbers together.
First turn: -16 points
Second turn: -5 points
Total score change: -16 + (-5) = -21 points
Therefore, after his first two turns, Malik's score has decreased by 21 points.
