Chapter 2, Problem 32E

a)

Program Plan Intro

Adding unsigned binary numbers:

To add two unsigned numbers some predefined rules should be followed. The rules are given as follows:

$\begin{array}{l}0+0=0\\ 0+1=1\\ 1+0=1\\ 1+1=\text{0}\text{(carry 1)}\end{array}$

$\text{1+1+1}\text{= 1 (carry 1) }$

b)

Explanation of Solution

Adding unsigned binary numbers 00010101 and 00011011:

Consider the two binary numbers. The addition two binary numbers should be performed from right to left.

$\begin{array}{l}00010101\\ +00011011\end{array}$

c)

Explanation of Solution

Adding unsigned binary numbers 01101111 and 00010001:

Consider the two binary numbers. The addition two binary numbers should be performed from right to left.

$\begin{array}{l}01101111\\ +00010001\end{array}$
