Binary Subtraction Rules
Binary Subtraction is performed in the same manner as decimal subtraction. However, there are some specific rules regarding the subtraction among the binary digits 0 and 1 which we need to follow while performingBinary Subtraction.

Binary subtraction is easily achieved using the rules added in the tab;le below,

0 – 0 |
0 |
When we subtract 0 from 0, we get 0 |
|
1 – 0 |
1 |
When we subtract 0 from 1, we get 1 |
|
0 – 1 |
1 (Take 1 from the following high order digit) |
When we subtract 1 from 0, we get 1 with a borrow of 1 |
|
1 – 1 |
0 |
When we subtract 1 from 1, we get 0 |
Addition of two binary numbers, 1 and 1, results in 10, where 1 is taken to the next high order and 0 is disregarded. However, nothing is carried over as the result of subtracting 1 from 1 is 0. When subtracting 1 from 0 in decimal subtraction, we borrow 1 from the preceding number to make it 10, and the outcome is 9 as 10 – 1 = 9. Nevertheless, binary subtraction yields just one result.
Binary Subtraction
Binary Subtraction is a mathematical operation and is one of the four fundamental operations of binary numbers. Binary subtraction is similar to decimal subtraction but the rules used as somewhat different.
