3. Adding and Subtracting Rational Numbers 2-2
Objective: Students will add and subtract integers and rational numbers.

4. Addition of Rational Numbers
Same sign – add their absolute values. The sign for the answer will be the same as the addends.
Example: (-7) = - 18

5. Addition of Rational Numbers
Different signs – subtract the lesser absolute value from the greater absolute value. The sum has the value of the greater absolute value.
Example: 8 + (-9) = -1

6. Guided Practice

7. Add
8 + (-5)
= 3
(-4)
= -5
= 8

8. Subtraction of Rational Numbers
Add its additive inverse: Take the sign of the largest number.
Example: 8 – 15 = 8 + (-15)
= -7

9. Subtraction -19 – 8 = -19 + (-8) = -27 2. 16 – (-23) = 16 + +23 = 39
3. – 9 – 6
= -9 + (-6) = -15
