# Octal Subtraction Calculator

## Subtract two octal numbers.

Binary tables offer a free octal subtraction calculator to help you
subtract octal numbers. Like octal addition, octal subtraction is at
times similar to the process you are familiar with in decimal
subtraction. The biggest difference between when octal subtraction and
decimal subtraction is where borrowing occurs. In octal subtraction,
borrowing happens within the same column (place value) when subtracting
a larger digit from a smaller one, adjusting with 8s as needed. This is
unlike decimal subtraction, which involves borrowing 10s between
columns. If you need to subtract octal numbers try our octal subtraction
