From 0 degrees Celsius, the
temperature increased by 5 degrees
in the morning. In the evening, it
decreased by 10 degrees. How can
we represent these values using
integers?

Integers consist of all positive whole numbers, negative whole numbers
and zero.
DEFINITION OF
INTEGERS
-3, -5, 0, 1, 7, and 18 are
integers.
1.6, ½, 5%, and -2.43 are
not integers.

INTEGERS ON A
NUMBER LINE
Fun Fact!
In a number line,
numbers are 
arranged from 
left to right in 
increasing order.
Negative numbers 
are on the left of 0.
Positive numbers 
are on the right of 0.
Zero is neither 
positive nor negative.
