How many cars can fit in the parking lot

  • 0:00 - 0:03
    The local grocery store opens at nine.
  • 0:03 - 0:05
    Its parking lot has six rows.
  • 0:05 - 0:07
    Each row can fit seven cars.
  • 0:07 - 0:08
    Each car has four wheels.
  • 0:08 - 0:11
    How many cars can the parking lot fit?
  • 0:11 - 0:14
    And I encourage you to pause the video
    and think about this yourself.
  • 0:14 - 0:17
    Try to figure it out on your own.
  • 0:17 - 0:18
    So, let's re-read this.
  • 0:18 - 0:20
    The local grocery store opens up at nine.
  • 0:20 - 0:24
    Well, that doesn't really matter. If we're thinking about
    how many cars can the parking lot fit.
  • 0:24 - 0:25
    So we don't really have to care about that.
  • 0:25 - 0:28
    We also dont have to care about
    how many wheels each car has.
  • 0:28 - 0:30
    They're not asking us how many
    wheels can fit in the parking lot.
  • 0:30 - 0:32
    So we can ignore that.
  • 0:32 - 0:34
    What we really care about is
    how many rows we have.
  • 0:34 - 0:37
    And how many cars can fit in each row.
  • 0:37 - 0:44
    What we have is -- We have six rows
    and each row can fit seven cars.
  • 0:44 - 0:47
    We're going to six groups of seven.
  • 0:47 - 0:48
    Or, another way of thinking about it.
  • 0:48 - 0:53
    We're going to have six times seven
    cars can fit in the parking lot.
  • 0:53 - 0:55
    What is this going to be equal to?
  • 0:55 - 0:59
    This is literally six sevens added up.
  • 0:59 - 1:05
    This is the same thing as
    one, two, three, four, five, six.
  • 1:05 - 1:08
    That last seven looks strange.
  • 1:08 - 1:13
    Now we're going to add these up.
  • 1:13 - 1:16
    Seven plus seven is fourteen.
  • 1:16 - 1:20
    Twenty-one, twenty-eight,
    thirty-five, forty-two.
  • 1:20 - 1:25
    Six times seven is equal to forty-two.
  • 1:25 - 1:31
    So forty-two cars can fit in the parking lot.
    Don't believe me? I made a little diagram here.
  • 1:31 - 1:33
    We have six rows.
  • 1:33 - 1:34
    This is the first row.
  • 1:34 - 1:35
    Second..
  • 1:35 - 1:36
    Third..
  • 1:36 - 1:37
    Fourth..
  • 1:37 - 1:37
    Fifth..
  • 1:37 - 1:39
    Sixth.
  • 1:39 - 1:42
    Each row can fit seven cars.
    You see it here.
  • 1:42 - 1:44
    One; Let me make that a little brighter.
  • 1:44 - 1:45
    One..
  • 1:45 - 1:46
    Two..
  • 1:46 - 1:47
    Three..
  • 1:47 - 1:50
    Four, five, six, seven.
  • 1:50 - 1:52
    How many cars are there?
  • 1:52 - 1:53
    You have seven.
  • 1:53 - 1:54
    Fourteen..
  • 1:54 - 1:56
    Twenty-one..
  • 1:56 - 1:57
    Twenty-eight..
  • 1:57 - 1:58
    Thirty-five..
  • 1:58 - 2:00
    Forty-two total cars.
  • 2:00 - 2:04
    Six rows of seven.
