# Booth bit-pair recoding technique

In Booth's bit-pair recording technique how to multiply a multiplicand with -2 or 2? For example while multiplying 01101(+13, multiplicand) and 11010(-6, multiplier), we get 01101 x 0-1-2.

How to multiply the multiplicand using -2?

• I thought the result is 1110110010, I do not fully understand your notation, shouldn't you recode the multiplier to 0-11-10? – Evil Aug 26 '16 at 0:34
