Subtracting Integers

2. Solve
The temperature in Anchorage, Alaska was 8°F in the morning and dropped to -5°F in the evening. What is the difference between these temperatures?
Solution
The distance from +8 to 0 is 8, and the distance from 0 to -5 is 5, for a total of 13.
=  +13. The difference is 13 degrees.

3. 4 Steps to Subtracting Integers
Rewrite the first number.
Change operation sign from subtraction to addition.
Change the second number to its opposite. – to +, + to –
Follow the rules for adding integers and solve.

4. Steps to Subtracting Integers
Example:
-9 – (-7) =
Rewrite the first number.
Change operation sign from subtraction to addition.
Change the second number to its opposite.
– to +, + to –
Follow the rules for adding integers and solve.
-9 – (-7) =
-9 + (-7) = =
= -2

5. Subtracting Integers 6 – 14 = -9 – (-11) = -5 – 10 = 31 – (-17) = -8 2
YOUR TURN….
6 – 14 =
-9 – (-11) =
-5 – 10 =
31 – (-17) = -8 2
