Day 3 Lesson

Integers Review

Integers is the set of numbers containing whole numbers and their opposites.

Integer

Integers can either be:

 

  •  Positive Integer – located at the right side of the number line
  •  Negative integers – located at the left side of the number line and has a negative sign (-)
  •  Zero – located in between positive and negative integers

In a number line, positive integers are located at the right side of zero (0) while the negative integers are located at the left side of zero (0).


CONCEPT ON NEGATIVE INTEGERS

 

negative integer is an integer that is less than zero. In the number line, these integers are located at the left side of zero (0).

 

Negative integers are the opposite of positive integers. For example, -2 is the opposite of 2. Even though both integers have the same number, they have different signs.


Solve these problems using the number line.
