**Evaluate - 3 + (-2)**

__Rule__: **To add two negative numbers, add their absolute values and take the negative sign for the answer**

**E.g. 1: -25 + (-17) = -42****E.g. 2: -21 + (-21) = -42****E.g. 3: -18 + (-11) = -29**

**~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~**

**Evaluate 3 + (-7)**

__Rule__: To add 2 integers of different signs such that the __negative__ integer has a larger absolute value, we find the difference between their absolute value and take the __negative__ sign for the answer.

**E.g. 1: -17 + 12 = -5****E.g. 2: 52 + (-67) = -15****E.g. 3: -88 + 85 = -3****E.g. 4: 28 + (-82) = -54**

__Rule__: To add 2 integers of different signs such that the __positive__ integer has a larger absolute value, we find the difference between their absolute value and take the __positive__ sign for the answer.

**E.g. 1: -12 + 17 = 5****E.g. 2: -63 + 68 = 5****E.g. 3: 86 + (-53) = 33****E.g. 4: -38 + 83 = 45**
