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. |

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