Basic Formula:
Sum = Number1 + Number2 + Number3
The calculator automatically handles positive and negative signs.
Rules for Adding Negative Numbers
Rule 1: Same Signs
If numbers have the same sign:
- Add their absolute values
- Keep the same sign
Example:
-5 + (-10) = -15
Rule 2: Different Signs
If numbers have different signs:
- Subtract smaller absolute value from larger one
- Keep the sign of the larger number
Example:
10 + (-4) = 6
Rule 3: Multiple Numbers
Add sequentially:
Example:
10 + (-5) + 3
Step-by-step:
- 10 – 5 = 5
- 5 + 3 = 8
Final Answer: 8
