Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If
Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed? 4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
I had the same question on my quiz and I believe it is -8 plus -8 plus -8 plus -8. Because that is equal to 4 times -8 or -32. Because he is descending so it has to be negative 8. And he is stopping 4 times every time he goes down 8.
