Convert decimal +47 and +31 to binary, using the
signed-2’s-complement representation and enough digits to
accommodate the numbers. Then perform the binary equivalent of
(+31)+(-47), (-31)+(+47), and (-31)+(-47). Convert the answers back
to decimal and verify that they are correct.

How is 00001001 (base 2) represented in 8-bit two’s complement
notation?
Convert 0.3828125 to binary with 4 bits to the right of the binary
point.
How is 00110100 (base 2) represented in 8-bit one's
complement.
1) Convert (0.513)10 to octal.
2) Given the two binary numbers X = 1010100 and Y = 1000011,
perform the subtraction (a) X - Y and (b) Y - X by using 2’s
complements.
4) Simplify the Boolean function and draw the logic diagram to
implement the function (i) F(a,b,c,d) = ∑(0,1,9,12,13,14) (ii)
F(a,b,c,d) = ∑(0,2,3,5,9,10,15) with don’t care d(a,b,c,d) =
∑(1,3,7,8,11,)
5) Implement the Boolean expression F (A, B, C, D) = _(1, 3,
4,7, 8,12, 13, 14, 15)...

(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)
