About Online Hex Calculator

Hexadecimal numbers are mostly used by system designers and programmers because they provide a convenient representation of binary-coded values. People in such professions are most likely to require a hex calculator.

What is a Hex Calculator?

In mathematics and computer science, hexadecimal also called “hex” is a number system with a base of 16. It uses 16 symbols with 0–9 and alphabetical letters A, B, C, D, E, F (or lower case a–f) to represent values 0 to 15.

Hexadecimal numbers are used mostly in a computing environment by system designers and programmers to convert between hexadecimal and binary notation for numbers. In such a case a hex calculator can be the best tool to use for doing calculations.

Hex Calculator is a free online tool that can perform arithmetic operations like addition, subtraction, multiplication, or division of hexadecimal values. Along with its arithmetic operations, it displays all the conversion values of hexadecimal numbers.

It is mainly used to perform arithmetic operations with hexadecimal numbers. Whether you want to add, subtract, multiply or divide hexadecimal numbers, the hex calculator tool does the calculation and displays the output in a fraction of seconds.

How does a Hex Calculator tool work?

Hex calculator has a nicely designed interface that helps you calculate multiple values into 4 different calculations such as multiplication, division, subtraction, and addition.

The working of hex calculator is as follows:

Step 1: Enter the 2 hexadecimal numbers in the text-box

Step 2: Click the button “Convert to Decimal & Binary” to convert hexadecimal to decimal or binary numbers. Note: The hex calculator first converts hexadecimal to decimal or binary numbers and then performs calculations to get the output.

Step 3: Finally, choose the arithmetic operations you want to add, subtract, multiply or divide and the result will be displayed in the output field

For doing hexadecimal calculations manually many would prefer using a hexadecimal table for small numbers and a base 16 calculator for large numbers. Hex calculator works the same way for hexadecimal numbers and giving results in seconds.

Hex Addition

Hex addition operation is calculated by converting between hexadecimal and decimal numbers. Hex calculator is actually performing the addition of decimal numbers at the same time converting from hex to decimal system when the values greater than 9 number is available.

Hex Subtraction

Hex subtraction can be calculated the same way as hex addition. But the difference involves borrowing as when borrowing in hex, the "1" that is borrowed represents 16decimal instead of 10decimal.

Hex Multiplication

Hex multiplication requires more effort when performing the operations. But Hex calculator makes it easy even with the large numbers.

Hex Division

Hex division operation is calculated by converting between hexadecimal and decimal numbers and performs long division in decimal, then convert back to hexadecimal once complete.
