#### Presentation Transcript

**1. **Using Counters Objective: Use counters to solve the addition of negative and positive integers.

**2. **Adding positive integers

**3. **Adding positive integers

**4. **Adding positive integers

**5. **Adding positive integers

**6. **Adding positive integers

**7. **Adding positive integers

**8. **Adding positive integers

**9. **Adding positive integers

**10. **Adding positive integers

**11. **Adding positive integers

**12. **Adding positive integers

**13. **Adding integers with different signs Rule: Subtract the absolute values of the integers. The difference will have the same sign of the integer with the greatest absolute value.
