Consider a 7 digit number in the form ABC- where A is 2-9 and X, B, and C can be any digit 0-9. Additionally B and C cannot both equal 1 since
these values are designated for other purposes such as services like 911.
Lastly 555-0100 through 555-0199 are reserved for fictional uses such as in
television shows or movies.
According to these conditions, how many 7-digit numbers are possible in a
single area code?
