As you travel to new planets in the space age, you discover a culture that does not use the digits 2,5,7,or 8. They would like to use 3-digit numbers for their zip codes, but they have superstition that beginning a zip code with zero brings bad luck to the people whom lives there. Can you help them figure out how many zip codes they can use?

Hint Begin by listing all the combinations that begin with 1. Hers's a start:

100 110 130 140 160 190
101 111 131 141 161 191
103
104
106
109
