What is the rule of negative and positive?
The Rules:
| Rule | Example | |
|---|---|---|
| +(+) | Two like signs become a positive sign | 3+(+2) = 3 + 2 = 5 |
| −(−) | 6−(−3) = 6 + 3 = 9 | |
| +(−) | Two unlike signs become a negative sign | 7+(−2) = 7 − 2 = 5 |
| −(+) | 8−(+2) = 8 − 2 = 6 |
What is the rule for dividing positive and negative integers?
