THE NUMBERS, EXPLAINED
How to use this calculator.
Treats inputs as a + bi and c + di. Division by zero is rejected.
Start with your inputs
Enter first real part, first imaginary part, second real part, second imaginary part, operation (+, -, *, /). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| First real part | 1 |
| First imaginary part | 2 |
| Second real part | 3 |
| Second imaginary part | 4 |
| Operation (+, -, *, /) | + |
A worked example
With the example inputs above, complex result is 4 + 6i. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Complex result | 4 + 6i |

Symbols and units
- a
- First real part
- b
- First imaginary part
- c
- Second real part
- d
- Second imaginary part
- e
- Operation (+, -, *, /)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
For (a+bi) and (c+di): add/subtract corresponding parts; product = (ac−bd)+(ad+bc)i; quotient = ((ac+bd)+(bc−ad)i)/(c²+d²). Division by zero is rejected.
Assumptions and limits
Treats inputs as a + bi and c + di. Division by zero is rejected.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Complex result. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Treats inputs as a + bi and c + di. Division by zero is rejected.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
