Say you want to multiply decimal integers:

$-13$ x $9$

using Booth's algorithm with $6-$bit operands

$($i$.$e$.-13$ is the multiplicand, and $9$ is the multiplier:

a$)$ What value would be stored in the $12-$bit product register

after the first pass?

b$)$ What value would be stored in the $12-$bit product register

after the second pass?

c$)$ What value would be stored in the $12-$bit product register

after the third pass?

d$)$ What value would be stored in the $12-$bit product register

after the fourth pass?

e$)$ What value would be stored in the $12-$bit product register

after the fifth pass?

f$)$ What value would be stored in the $12-$bit product register

after the sixth $($final$)$ pass?$+$
