To multiply hex numbers, you work digit by digit, as you do with decimal
  numbers. To make multiplication easier, use Figure B-7, which shows the
  product of any two hex digits. To use the table, find the row for one hex
  digit and the column for the other. The hex number located at the
  intersection of the row and column is the product of the two digits.
