In the octal (base 8) number system, to represent integers we use the symbols $0,1,2,3,4,5,6,$ and $7 .$ In representing an integer, reading from the right, the first symbol represents the number of I's, the next symbol the number of 8 's, the next symbol the number of $8^{2}$ 's, and so on. In general, the symbol in position $n$ (with the rightmost symbol being in position 0 ) represents the number of $8^{n}$ 's.
