Hi Billy, Think about starting at zero and taking a number of steps along the number line where a positive number means you step to the right and a negative number means you step to the left. In your third problem you take 19 steps to the right then 20 steps to the left.
You finish at -1 so
Now try the second problem. If you start at zero and take 38 steps to the left then a further 22 steps to the left where do you finish? Now try problem 1. Penny |
