One extra bit is added on the left of a binary number, in case of Binary Multiplication using Booth’s Algorithm.

(a) True

(b) False

I had been asked this question during an online exam.

This intriguing question comes from Booth’s Algorithm topic in section Computer Arithmetic of Computer Fundamentals

Best answer
The correct option is (a) True

For explanation: The statement is true as an extra bit is added when we multiply 2 binary numbers by using Booth’s.

Let us take an example if we multiply 2  * – 3.

The first step is to obtain the binary equivalents.

Hence, 2=10 and -3=01.

Now after adding the extra bit 2=010 and -3=101.

We add 0 in case of positive numbers whereas 1 in negative numbers.
