If one of the numbers you are multiplying by is negative,then that answer will be negative.
To find the median cancel out numbers on both sides, until one is left in the middle and if there are two in the middle add them up and divide by two.
So in this case the median is
53+78
131 / 2
65.5
8 inches
Divide 56 by 7 which equals 8 so Fred's frog jumped 8 inches.
