Octal subtraction: The rules for subtracting two octal numbers are as follows: Read both the numbers to know the number of bits. If the number of bits in the first number is less than that of the other number, add the required number of zeros on the left side. Numbers are represented in bytes where one byte is equal to 8 bits. Align the number in correct order after padding. The octal number that is followed by a minus sign should be subtracted from the other octal number.

Explanation of Solution

b.

“1234 – 765”:

Start numbers from right to left.

Subtract “5” from “4”.

Here “4” is less than “5”. As a result, borrow a number from adjacent left hand side.

After borrowing it becomes “2” as adjacent left side number is “3”.

After borrowing, add “8” with “4”.

Add “8” with “4” and then subtract it from “5”, which give “7”. The equivalent octal number for number “7” is “7”. Hence, write “7” to the result.

Subtract “6” from “2”.

Here “2” is less than “6”. Borrow number from adjacent left side.

After borrowing, it becomes “1” as adjacent left side number is “2”.

After borrowing, add “8” with “2”.

Add “8” with “2” and then subtract this from “6”, which give “4”...
