Lanette walked forward 9 steps, backward 15 steps, forward 7 steps, and backward 8 steps. How many steps is lanette from where she started?

We use (+) for forward steps and (-) for backward steps
  • Forward 9, backward 15 is: +9 - 15 = -6
  • Forward 7 steps is: -6 + 7 = +1
  • Backward 8 steps = +1 - 8 = -7
Since negative is backward and positive is forward, we see Lanette is 7 steps backwards from her starting point.
