'''Perform the Following Steps:'''
# Let's convert the following ''8-bit'' binary number '''10111110''' to a '''<u>decimal number</u>'''.<br><br><span style="color:blue;">'''NOTE:''' It is important to learn and '''memorize''' the '''correct methods''' to perform the<br>proper numbering conversion method (i.e. view '''method 1''' above (drawing the L's).</span><br><br>
# Write the manual conversion either in your MS Word document.<br><br>
# Use a '''calculator''' to check your work. In MS Windows, you can set the calculator to Programming mode<br>by making the selection to '''binary''', enter the binary number '''10111110''' and view the decimal equivalent.<br><br>Did you get the correct answer? If not, <u>retry</u> the method and check to see what you did wrong.<br><br>
# Perform a manual conversion of the '''decimal number 55''' to an a '''<u>8-bit binary number</u>'''.<br>What method (displayed above) will you use? Use a calculator to check your work.<br><br># Perform a manual conversion of the '''octal number 461''' to an a '''<u>8-bit binary number</u>'''.<br>What method (displayed above) will you use? Use a calculator to check your work.<br><br># Perform a manual conversion of the '''8-bit binary number 11110001''' to a '''<u>hexadecimal number</u>'''.<br>What method (displayed above) will you use?
