Welcome to MooMooMath where we upload a new
Math video everyday
In this video I would like to talk about integers.
Integers include all whole numbers
(0, 1, 2, 3, ....) and their opposites.
Integers do not include fractions, or percents,
or decimals.
Integers can describe opposite situations.
A positive integer would be a deposit of $50.
A negtive interger would be a withdraw of
50 dollars
A positive integer would be 200 ft. above
sea level.
A negative integer would be 200 feet below
sea level
A number & its opposite are the same distance
from 0!
Lets look at another example.
What integer represents a gain of 35 yards?
35
What is the opposite of a gain of 35 yards?
A loss of 35 yards?
-35
What does zero represent in this situation?
You didn’t gain or lose yards
Next lets talk about, Ordering & Comparing
Integers
Use a number line when ordering and comparing
integers.
The number furthest to the left is the least
number.
The number furthest to the right is the greatest
number
As you move to the right the integers are
positive and to the left of zero the integers
become negative.
For example, compare -9 and 4
-9 less than 4
0 greater than -3
-4 greater than -7
Order these integers from least to greatest.
-2, 8, -5
from least to greatest -5 -2 8
0, -6, 10 would be -6, 0, 10
-8, -2, -6
would be from least to greatest -8 -6 -2
Thanks for watching, hope this video helped
with integers.
