## How to Add Numbers of Different Bases

The first step to add numbers of a different base is to convert the number to decimal. Our binary to decimal, hex to decimal, or octal to decimal can help with this.

Then, add the numbers together like you normally would.

And finally, convert from decimal to the desired number base. You can use a decimal to binary, decimal to hex, or decimal to octal converter for this task.
