7 – For the following operations:
• write the operands as 4-bit 2's complement binary numbers,
• perform the operation shown,
• show all work in binary operating on 4-bit numbers, and
• identify overflow if necessary.
a) 4 + 2
b) 4 – 2
c) 2 – 4
d) 4 + 4
(a) Do operation 75.38 - 18.62 in binary using two's complement.
Use for the fractional part 6 bits
(b) Convert the resulting expression to decimal, and say how much
is the absolute error obtained in the operation.
The standard method of representing negative numbers in the
binary system is with 2's complement notation. What are the
advantages and disadvantages of using this method to represent
negative numbers?
(a) Convert the decimal numbers, 70 and -26 to binary in the
signed 2’s complement system. Make sure there are enough digits in
the results to be able to perform arithmetic operations with these
two numbers.
(b) Perform in the signed 2’s complement system, (+70) +
(-26)
(c) Perform in the signed 2’s complement system, (-70) -
(-26)
(d) Perform in the signed 2’s complement system, (+70) +
(+26)
Part 1: Solve the operation 75.38-18.62 in binary
using two's complement. Use 6 bits for the fractionary part.
Part 2:Convert the result to a decimal, and explain
how much is the absolute error obtained in the operation.
(Provide Step by Step process of problem solving in
each part.)
Find the decimal equivalents for the following 8-bit
two’s complement numbers.
a. 0010 0100 Decimal Equivalent ___________
b. 1010 1001 Decimal Equivalent ___________
c. 1100 0011 Decimal Equivalent ___________
d. 0101 0101 Decimal Equivalent ___________
i need to convert decimal to twos complement binary and then add
the binary digits but I am unable to do it. I am only allowed to
use string, can anyone help me out please. i need the code
urgently.

For each of the following determine whether ∗ is a binary
operation on R. If so, determine whether or not ∗ is associative,
commutative, has an identity element, and has inverse elements.
(a) a ∗ b = (ab) / (a+b+1)
(b) a ∗ b = a + b + k where k ∈ Z
(c) a ln(b) on {x ∈ R | x > 0}
