Davion says walking to the Right 7 steps and then 9 steps to the left is represented by -7 + 9 because you always need to start a zero and then go to the left as much as possible. Is Davion right? Explain your answer.
1) Davion says walking to the Right 7 steps
so
+7
2) and then 9 steps to the left
so
+7-9=-2
therefore
Davion is wrong
because
to the right is positive and to the left is negative
walking to the Right 7 steps and then 9 steps to the left is the same that walking to the left 2 steps
