Adding Integers
 Absolute Value = Distance from zero
 Example:
 Pos + Pos = Pos
Example: 2 + 3 = 5
 Neg + Neg = Neg
Example: -2 + -3 = -5
 Neg + Pos =
 Pos + Neg =
1. Find the difference between the
two numbers
2. Take the sign of the number with
the greatest absolute value
 Example: -2 + 3 = 1
2 + -3 = -1

Subtracting Integers
 Subtracting a positive number is the same as adding a
negative Example: 5 – 7 = 5 + -7
 Subtracting a negative number is the same as adding a
positive
Example: 7 - -5 = 7 + 5
 Using the above rules, change your
problem from a subtraction to an
addition problem
 Then solve using the addition rules!

Order of Operations
(5 – 7) + 23 ÷ 4 x 2 – 6
(5 – 7) + 23 ÷ 4 x 2 – 6
3
-2+ 2 ÷ 4 x 2 – 6
-2+ 8 ÷ 4 x 2 – 6
-2+ 2 x 2 – 6
-2+ 4 – 6
2 – 6 = 2 + -6 = -4
