Integers are numbers that are positive, negative, or zero and do not have decimals or fractions. Integers are used to represent things like temperature, money, and scores. Negative integers are added by ignoring the negative signs and putting the negative sign in the answer. To add integers with different signs, use the absolute value and subtraction. Absolute value represents the positive value of a number.

2. ABOUT IT
Integer is a group of positive number(above
0),0,negative number(below 0)
Symbol of negative number is donated as (-)
Symbol of positive number is donated as (+)
integers do not have
decimals
Integers do not have
fractions

3. Examples
Integers non integers
1. 44 -4.7
2. -6 4 6/7
3. -8894 3.56
4. 33 2.7
5. 998 1.2

4. Place where Positive and Negative
Integers used
Positive no.
• When the temperature
is above zero
• When you are above
ground
• When you earn money
• In hockey, when your
team scores a goal
while you are on the ice
Negative no.
• When the temperature
is below zero
• When you are below
ground
• When you spend
money
• In hockey, when the
other team scores a
goal while you are on
the ice

5. Adding negative integers
• Adding negative integers is just like adding
positive integers…only difference…the
answer will have a negative sign
• -6 +(-5) = -11
• All you do is ignore the negative signs and
add the numbers, then put the negative sign
back in your answer
• THIS ONLY WORKS IF BOTH NUMBERS ARE
NEGATIVE!!

7. Adding integers with different signs
• On the previous slide we saw a diagram of
the problem 6 + (-2)
• To solve this, they started at zero and moved
to the right 6 places – to represent the
positive 6
• Next, they moved left 2 places – this
represented the -2
• They landed on the number 4 (positive 4)
which is the answer

8. Absolute value
• Using a number line is a great way to
practice when you are first learning to
add numbers with different signs – but
there is another way
• We can use the absolute value of a
number and subtraction to solve
addition problems involving integers of
different signs

9. Absolute value
•It is written as vertical lines on
either side of a number
•|12|, is 12
•|-23|, is 23
•Absolute values are ALWAYS
positive
