(4) Binary to decimal conversion. Binary to decimal conversion is really
quite easy. To determine the decimal equivalent, simply add up the values of the
places marked by binary one.
Figure 1-15. Adding up the values of the places marked by binary one
will give you the decimal equivalent.
(a) Note that since the third place to the left is occupied by a zero, we
did NOT add in the value of that place (22 x 0 = 0). Only places marked by binary 1 are
added in. Let's try another example: binary 1001. This time you do the calculations.
Follow the same steps as in the preceding example. Enter your computations below.
