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
