on dh don't get us started on complex carbohydrates What
- 00:28
do we do when something makes our heads Thanks but
- 00:33
way simplified We break things down into more manageable pieces
- 00:41
when something is overwhelming way just have to divide and
- 00:44
conquer what such is the story when it comes to
- 00:47
crime factories Ation So what are we shooting for What
- 00:55
numbers are easiest to work with Why That would be
- 00:58
the prime numbers of course numbers that are divisible only
- 01:02
by themselves and one what could be simpler For example
- 01:10
three can be divided by three and one So it's
- 01:13
a prime number Four on the other hand can be
- 01:17
divided by four one and two so it is not
- 01:21
a prime number You don't have to know all of
- 01:25
the prime numbers Whoa thank goodness there's an infinite number
- 01:29
of them Say what but it will be helpful to
- 01:32
familiarize yourself with at least the first ten who they

- 01:42
large number down into these puppies you have the number
- 01:48
thirty Well any time you start with an even number
- 01:51
the first thing you can do is divide by two
- 01:53
In this case our results fifteen can also be simplified
- 01:57
It isn't invisible by our first prime number but is
- 02:00
divisible by the necks one on our list and suddenly
- 02:02
we're left with three prime numbers Well here we can
- 02:06
say that two three and five are factors of thirty
- 02:10
because each of them can be divided into the number
- 02:12
evenly uh now instead of that fat number thirty We
- 02:19
have whittled it down to its most basic components You'll
- 02:22
find that this skill will come in handy in a
- 02:24
wide variety of mathematical applications such as reducing fractions Yes
- 02:29
just just just just We're dealing with triangles that have
- 02:32
really long side done done so get you know the 00:02:38.44 --> [endTime] prime number simplify your life
