<b>Explanation:</b> Look at the Binary Number Bit Status row in the chart below. If there is a 1 in a position add the value shown. If there is a 0 (zero) in a position then do not add it. Note that eight bits cannot represent a decimal number greater than 255 (If all eight positions are 1s then 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255).</p>
