My thousands digit is the first that is perfect.but if you're not happy with that,it's also the product of the first two primes,according to my precocious cat.
My units digit is the odd of those primes,and if you look at it and my tens,you'll find a number divisible by three,but not by the square of that,friends.
Now let's look at my hundreds and thousands.If you examine those two as they're paired,you'll find they form a divisible by an even prime that's been squared.
Now let's look at my body in whole.Five different dights you see,in order (or not) you'll find that they are divisible by nine,yes siree!
Can you find the mystery number?

why did you decide to major in math? do you think that the ability to succeed as a math major is innate...or can anyone with a reasonably high level of intelligence do well in it if they have the desire to work hard? i am just wondering because i am considering going back to university and i remember liking my math classes, even though i didn't do well in them because i was un-motivated. but now that i'm more motivated to go back to school and work hard, i'm wondering if math is for me. i really want to succeed at whatever i do! how do i know if i will succeed in math?

Make a table of input and output. The output is the sum of the input and 2 if the input is even. The output is the product of the input and 2 if the input is odd. Use integer inputs 0 through 8.
