Mathematical Formulas Used in the Calculator
The calculator performs four basic arithmetic operations. Let’s understand the formulas behind them.
1. Addition (+)
Addition combines two numbers into a total value.
Formula:
Result=A+B
Example:
A = 500000000000000
B = 200000000000000
Result = 700000000000000
2. Subtraction (−)
Subtraction finds the difference between two numbers.
Formula:
Result=A−B
Example:
A = 900000000000000
B = 300000000000000
Result = 600000000000000
3. Multiplication (×)
Multiplication calculates repeated addition of numbers.
Formula:
Result=A×B
Example:
A = 100000000000000
B = 2
Result = 200000000000000
4. Division (÷)
Division splits a number into equal parts.
Formula:
Result=BA
Condition:
B ≠ 0 (division by zero is not allowed)
Example:
A = 100000000000000
B = 2
Result = 50000000000000
Example Calculation Table
| Operation | Input A | Input B | Result |
|---|---|---|---|
| Addition | 100000000000000 | 200000000000000 | 300000000000000 |
| Subtraction | 500000000000000 | 100000000000000 | 400000000000000 |
| Multiplication | 100000000000000 | 3 | 300000000000000 |
| Division | 800000000000000 | 2 | 400000000000000 |
