Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go. If Yan made 8 stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan climbed? 4 4 4 4 8 8 8 8 (Negative 1) (4 4 4 4) (Negative 8) (negative 8) (negative 8) (negative 8)
