No attempt at these 4 teasers yet.

1. Which two numbers can complete the series 12, 33, 66, ___, 363, 999, ____ ?

2. What number, when multiplied by itself, will result in a number containing every digit from 1 through 9, and from 9 back through 1, in numerical order?

3. The following note found in a bottle was brought to the attention of a brilliant professor by one of his students. The latter challenged the learned man to figure out : who was the famous sea captain who wrote the poem contained in the note below?

"A mighty ship I now command,

With cargo rare from every land.

No goods have I to trade or sell;

Each wind will serve my turn as well;

To neither port nor harbor bound,

My greatest wish to run aground."

4. Using each of the division, multiplication, addition and subtraction signs only once with the numbers 4, 5, 6, 8, and 9. How does one arrive at one as the answer?
