Okay, we have five shapes here.
00:04
And we're talking about how many different options we have to go from left to right.
00:11
So if we were to arrange this, we would have five different spots.
00:16
And so for this first spot, we would have five options to choose from.
00:22
But once that guy's taken up, now we only have four options for our next spot, three for our next two.
00:29
And then by the time we get to this last spot, there's only one shape left.
00:35
So if we want to find our total options, we're going to multiply these numbers together, and we get 120.
00:45
So that would be from left to right.
00:48
If we're talking about from top to bottom, we would have one on the top, next, next, next, next.
00:55
Next, but it would be the same thing.
00:59
Five, four, three, two, one...
