Olye ke l x au plus y au plis z au, mwen te pale a tou r au, jis ti jan fè pou ou a, entwisyon an sa sa espresyon di ti lakou a distans kòm nou chape nan mitan de chanm nou, ou de la koòdone 0, 0, 0.

Instead of x squared plus y squared plus z squared, I wrote r squared, just to kind of give you the intuition that this expression is just saying the square of the distance as we get away from the center of our room, or from the coordinate 0, 0, 0.
