Q. Read this word problem.

\newline

Bryant was playing the video game Ship, Ship Ahoy! He began Level

2

with

15

points but soon got

-6

points because his character fell overboard. What is Bryant's total score now?

\newline

To solve the problem, Will added

15 + (-6)

and came up with an answer of

-9

. Is Will correct? Why or why not?

\newline

Choices:

\newline

(A)Yes, Will is correct.

\newline

(B)No. The answer should have been

9

, not

-9

, because Bryant had more points to start than he lost when he fell overboard.

\newline

(C)No. Will should have subtracted

-15 - (-6)

because Bryant got negative points.

\newline

Calculate starting points: Bryant started with $15$ points and then lost $6$ points, so we need to subtract the points he lost from his starting points. Let's do the math: $15 + (-6)$ .
Subtract points lost: Adding $15$ and $-6$ gives us $15 - 6$ , which equals $9$ .
Final score calculation: So, Bryant's total score now is $9$ points. Will's answer of $-9$ is incorrect because when you lose points, you subtract, and subtracting a negative is like adding a positive.
