Formula for Binary Addition
Binary addition follows the same concept as decimal addition but only uses two digits: 0 and 1.
Basic Binary Addition Rules:
| Binary Input | Result | Carry |
|---|---|---|
| 0 + 0 | 0 | 0 |
| 0 + 1 | 1 | 0 |
| 1 + 0 | 1 | 0 |
| 1 + 1 | 0 | 1 |
Conversion Formula Used in Calculator
The calculator internally converts binary numbers into decimal:
Step 1: Binary to Decimal Conversion
Each binary digit represents a power of 2:
Binary → Decimal Formula:
( bₙ × 2ⁿ ) + ( bₙ₋₁ × 2ⁿ⁻¹ ) + … + ( b₀ × 2⁰ )
Step 2: Decimal Addition
Decimal1 + Decimal2 = Total Sum
Step 3: Convert Back to Binary
Final result is converted back:
Decimal → Binary using base 2 conversion
Example of Binary Addition
Let’s understand how the calculator works with an example.
Input Values:
- Binary Number 1: 10101
- Binary Number 2: 11011
Step 1: Convert to Decimal
| Binary | Decimal |
|---|---|
| 10101 | 21 |
| 11011 | 27 |
Step 2: Add Decimal Values
21 + 27 = 48
Step 3: Convert Back to Binary
48 in binary = 110000
Final Result:
| Output Type | Value |
|---|---|
| Binary Sum | 110000 |
| Decimal Sum | 48 |
| Operation | 10101 + 11011 |
Binary Addition Table (Quick Reference)
| Binary 1 | Binary 2 | Sum (Binary) | Decimal Result |
|---|---|---|---|
| 1 | 1 | 10 | 2 |
| 10 | 11 | 101 | 5 |
| 101 | 10 | 111 | 7 |
| 1001 | 111 | 10000 | 16 |
| 1101 | 1011 | 11000 | 24 |
