Question

Rebecca is playing a video game that involves planting and cutting down trees. She moves up an energy level for each tree she plants, and she moves down a level for each tree she cuts. If Rebecca reaches energy level 10, she will earn bonus points.

Rebecca is currently at energy level 4. The results of her next 3 turns are:
Turn 1: 6 trees cut
Turn 2: 8 trees planted
Turn 3: 1 tree cut

Answer the questions to find out whether Rebecca earned bonus points in the next 3 turns. Use the number line to help you add.

Answer 1

She does not get bonus points and she ends up at level 5.

Equation: 4 - 6 + 8 -1 = 5

Equation using only addition: 4 + -6 + 8 + -1 = 5

I hope this helps!
