hey guys it's kaylee in this lesson we're going to work with negative numbers
and learn ways to order them from least to greatest or greatest to least let's go
first of all what is a negative number sounds very mysterious right the answer is simple
it just means a number that is less than zero so let's get out our number line now let's say
today it's gonna be cold outside it's only two degrees now what if tomorrow is supposed to be
three degrees colder than today well if it's one degree colder it would be
one degrees and if it was two degrees colder it would be zero degrees but if it's three degrees
we need to go one more over and what is that number one less than zero is called negative one
so here is a full number line if this point
is 0 also called the origin then you know that everything going to the right of 0 is
a positive number and that means everything going to the left of 0 is a negative number
in this lesson we're really focused on this half of the number line
and which negative numbers are larger or smaller here's the number one rule for negative numbers
the closer the negative number is to zero on the number line the bigger the number
is another way to think about this is to say numbers increase as we go
to the right on the number line this is true for negative and positive numbers
so let's take a look at these negative numbers we need to order them from least to greatest
and that means smallest to largest so what number do you think is the largest
our first rule says the negative number closest to zero is the biggest number what number here
is closest to zero well if i have negative two right here and i have negative one right here
and negative 4 is over here i can see which one of these numbers is closest to 0.
yeah that's right negative 1 is the closest to 0.
so that goes to the end of our list it's the greatest number one greatest
now which is the next closest to zero negative two or negative four well negative two is only two
spaces away and four is over here at four spaces away so negative two is the next closest to zero
so that would mean negative 4 is the smallest number in our list so when we order these
from least to greatest we have negative 4 negative 2 and then negative 1.
awesome work are you ready for some practice let's do practice problems together in the
next video called ordering negative numbers have fun and remember to always be clever
