Question Regarding binary and hexadecimal

[jayshaw94]

Quick question
For one of my classes I received 2 questions.
I'm having a bit of trouble understanding the questions. Help would be awesome

Question 1:

Using the built in Calculator function in Windows (Start, Calc) from the programmer's view menu drop down:
CONVERT 91 BASE 10 to a BINARY Number and to a HEXADECIMAL Number (Replace the X's below).

Answer: 9110 converts to
XXXXXXX2
XX16



If anyone has the answer to this could you please explain how you got the answer
Question 2:

A truth table follows the rules of logic that were used by Greek philosophers in searching for truth and were then used by George Boole in a mathematical manner as follows:
0 and 0 = 0; 1 and 1 = 1; 0 and 1 = 0
0 or 0 = 0; 1 or 1 = 1; 0 or 1 = 1

COMPLETE THE FOLLOWING TRUTH TABLE
Answer
1 AND 1
0 OR 1
1 AND 0
0 OR 1

If anyone has the answer to this could you please explain how you got the answer

For the first one, simply switch the calculator to programming mode, then use the buttons on the side to bin or hex or dec (binary, hexadecimal, or decimal respectively)

and that truth table, well you are given the answers. Just match the statement above to the one below.

Thank you
I thought it was a difficult quesiton

no, they only really get complicated once you must simplify them, and even then, it's quite simple.
