Hexadecimal arithmetic comes up constantly in programming (memory addresses, color codes, byte values), but combining two hex values by hand means either memorizing hex addition tables or converting through decimal each time.
This calculator performs arithmetic and bitwise operations on two hexadecimal numbers, converting through decimal and back.
How it works
Enter two hexadecimal numbers and choose an operation. The calculator converts both to decimal, performs the chosen arithmetic or bitwise operation, then converts the result back to hex.
- Enter first hex number.
- Enter second hex number.
- Enter operation.
- Click Calculate to see your results.
Examples
1A + F
Adding hex 1A (decimal 26) and hex F (decimal 15) gives hex 29 (decimal 41).
Who should use it
- Checking hex arithmetic for a computer science or programming course.
- Combining hex color values or memory addresses using bitwise operations.
Industry applications
- Software development and computer science education
- Low-level programming and systems work
Advantages
- Supports both arithmetic and bitwise operations in one tool.
- Shows the decimal equivalent at every step for easy verification.
Limitations
- Limited to reasonably sized hex inputs — very large hex numbers should be handled with a general-purpose big-number tool instead.
Common mistakes to avoid
- Including a "0x" prefix in the input, which isn't needed and isn't valid hex digit syntax on its own.
- Entering digits outside A-F and 0-9, which aren't valid hexadecimal characters.
Best practices
- Double check results against the decimal values shown in the step-by-step solution, especially for bitwise operations which are easy to miscalculate by hand.
Tips
- Bitwise AND with 0xFF is a common way to isolate just the lowest 8 bits (one byte) of a larger hex value — useful when working with color channels or byte-level data.
