The map in words
- Start: Multiply Two Integers
- What are the signs?
- Both positive: Positive × Positive
- Result is POSITIVE
- Example: 5 × 4 = 20
- Multiply absolute values, keep positive sign
- Example: 5 × 4 = 20
- Result is POSITIVE
- Both negative: Negative × Negative
- Result is POSITIVE
- Example: -5 × -4 = 20
- Result is POSITIVE
- One positive, one negative: Mixed Signs
- Result is NEGATIVE
- Example: 5 × -4 = -20
- Multiply absolute values, attach negative sign
- Example: 5 × -4 = -20
- Result is NEGATIVE
- Both positive: Positive × Positive
