Mathematical Formula Explanation
The 8×8 Calculator works based on standard arithmetic principles used in mathematics. Below are the key formulas behind its operations:
1. Addition Formula
A + B = Result
Example: 5 + 3 = 8
2. Subtraction Formula
A – B = Result
Example: 10 – 4 = 6
3. Multiplication Formula
A × B = Result
Example: 6 × 7 = 42
4. Division Formula
A ÷ B = Result
Example: 20 ÷ 5 = 4
5. Decimal Calculation
The calculator also supports decimal operations:
Example: 2.5 + 1.5 = 4.0
Order of Operations (Important Concept)
The calculator follows a standard mathematical rule known as BODMAS (or PEMDAS in some regions):
- Brackets
- Orders (powers and roots)
- Division
- Multiplication
- Addition
- Subtraction
This ensures that calculations are performed in the correct order for accurate results.
For example:
5 + 3 × 2 = 11 (not 16)
Because multiplication is performed before addition.
Example Calculations
Here are some real-life examples of how the calculator works:
Example 1: Simple Addition
Expression: 25 + 15
Result: 40
Example 2: Mixed Operations
Expression: 50 – 10 × 2
Step-by-step:
- 10 × 2 = 20
- 50 – 20 = 30
Final Result: 30
Example 3: Division and Multiplication
Expression: 100 ÷ 4 × 3
Step-by-step:
- 100 ÷ 4 = 25
- 25 × 3 = 75
Final Result: 75
Example 4: Decimal Use
Expression: 7.5 + 2.3
Result: 9.8
Calculation Table for Better Understanding
| Expression | Step Calculation | Final Result |
|---|---|---|
| 12 + 8 | 12 + 8 | 20 |
| 15 – 5 | 15 – 5 | 10 |
| 6 × 7 | 6 × 7 | 42 |
| 20 ÷ 4 | 20 ÷ 4 | 5 |
| 9 + 3 × 2 | 3 × 2 = 6 → 9 + 6 | 15 |
| 18 ÷ 3 + 4 | 18 ÷ 3 = 6 → 6 + 4 | 10 |
This table helps users understand how different operations are solved step-by-step.
