Detailed explanation-1: -That means the last digit of the answer will be one. Then we move one digit to the left: adding 1 and 1 we get 10. Hence, the answer is 101.
Detailed explanation-2: -In the binary or base 2 number system, there are only two digits, 0 and 1 . This means that unlike in the denary number system 1 + 1 does not equal 2, it equals 10 . Look at the following rules that apply when adding binary numbers together: 0 + 0 = 0.
Detailed explanation-3: -Note: The binary product of the two binary numbers 1 and 1 is equal to 1 only.
Detailed explanation-4: -Rules and tricks: Binary subtraction is much easier than the decimal subtraction when you remember the following rules: 0 – 0 = 0. 0 – 1 = 1 ( with a borrow of 1) 1 – 0 = 1.
