Question

During the first round of a game, Silas scores 15 points. He loses 30 points during the second round and gains 10 points during his final turn. What is Silas’ final score? A. –55 B. –25 C. –5 D. 55

Answer 1

C. -5

Explanation:

Imagine a number line from -15 to 15.

Start at 15, and go left for 30 hops, since we are subtracting. This gives us -15.

Now, start at -15. We go right for 10 hops since we are adding. Where do we land? -5. Thus giving us our answer.

Or you can do it this way:

15-30= -15

-15+10= -5

-5
