Mathematical Formula Explanation
This Signs Calculator is based on fundamental arithmetic formulas used in mathematics:
1. Addition (+)
Formula:
Result = a + b
Example:
If a = 10 and b = 5
Result = 10 + 5 = 15
2. Subtraction (−)
Formula:
Result = a − b
Example:
If a = 10 and b = 5
Result = 10 − 5 = 5
3. Multiplication (×)
Formula:
Result = a × b
Example:
If a = 10 and b = 5
Result = 10 × 5 = 50
4. Division (÷)
Formula:
Result = a ÷ b
Example:
If a = 10 and b = 5
Result = 10 ÷ 5 = 2
⚠️ Note: Division by zero is not allowed, as it is mathematically undefined.
