Instructions
READ THESE INSTRUCTIONS CAREFULLY!
Answer each question carefully. Since this is automatically graded, partial credit will not be possible.
You may have ONE sheet of blank paper. Show BOTH sides to the camera BEFORE starting the
exam.
No notes. No calculator. No electronics of any kind. No books. Just you, your pencil, and your
computer to access the quiz.
No headphones or earbuds or listening devices of any kind other than the computer on which you are
taking the quiz.
IMPORTANT: Do NOT include the subscripts for numbers. If I ask for a binary answer, just put
the 0s and 1s. If I ask for a hex answer, just put the hex digits. For example, 1011 or FA. This
quiz is automatically graded and your answer will be counted incorrect if you include the
subscripts!
Do not discuss this quiz until after the quiz closes at 11:59 p.m. Because of past experience, I
have to be clear: do not discuss this with other students, family members, family pets, pet
rocks, flying squirrels, or imaginary friends. Any such discussion will be considered a
violation of the academic integrity policy. Note that the questions come from a question bank
so it is very unlikely you'll have the same questions as your friends anyway...

Add the following two's complement binary numbers. What is the decimal value of each addend?
What is the decimal value of the sum? Is there overflow? (Remember that when there's overflow, the
sum doesn't match what is expected from the addition. Show the decimal value of the binary sum, not
what was expected from adding the decimal values.)
