Which one of the following expresses the decimal number 74 in binary arithmetic? And why please?
(Not that I’m a big proponent of answering exam questions directly, but…) 1. Launch Windows Calculator (Programs > Accessories > Calculator, or Start > Run > calc.exe). 2. Change View to Scientific mode (View > Scientific). 3. Ensure the the “Dec” radio button is selected. 4. Enter 74. 5. Click the “Bin” radio button. 6. See that “1001010” or option “d” is your answer. 7. Rinse and repeat.
