Unformatted text preview: 10 and subtract to see if the answers correspond. Power of Two Number Systems Binary and octal numbers have a very special relationship to one another: Given a number in binary, you can read it off in octal and given a number in octal, you can read it off in binary. For example, take the octal number 754. If you replace each digit with the binary representation of that digit, you have 754 in binary. That is, 7 in octal is 111 in binary, 5 in octal is 101 in binary, 4 in octal is 100 in binary, so 754 in octal is 111101100 in binary. To facilitate this type of conversion, the table below shows counting in binary from 0 through 10 with their octal and decimal equivalents....
