What is the difference between a full-adder and a half-adder?
Subtract the following binary numbers.
The selector inputs to an arithmetic/logic unit (ALU) determine the:
Divide the following binary numbers.
Half-adders can be combined to form a full-adder with no additional gates.
It is not necessary to have the same number of bits when adding or subtracting signed binary numbers in the 2's-complement system.
Digital computers use an easier method to subtract binary numbers, called one's complement.
An ALU is a multipurpose device capable of providing several different logic operations.

Solve this BCD problem: 0100 + 0110 =
The carry propagation delay in 4-bit full-adder circuits:
Perform subtraction on each of the following binary numbers by taking the two's-complement of the number being subtracted and then adding it to the first number.01001 0110000011 00111
A sign bit of "1" in the difference of a 2's-complement subtraction problem indicates the magnitude is negative and in true binary form.
The solution to the BCD problem 0101 + 0100 is 00001001BCD.

Full adder results are typically stored in registers.
The representation of –110 in eight-bit two's-complement notation is 11110111.
Binary multiplication is like decimal multiplication except you deal only with 1s and 0s.
The solution to the binary problem 1011 – 0111 is 1000.
BCD arithmetic is performed using base 10 numbers.
