Pyramid

Since I do not have time for a new puzzle, I'll post something which people can comment on. 

Steve flips a coin, 
If tail appears in the first flip, you receive $2, if tail appears in the second flip, you receive $4, if tail appears in the third flip, you receive $8, if tail appears in the fourth flip, you receive $16, etc. The money will keep on doubling until you hit a tail. 

How much would you be willing to pay to play this game?

I am not sure what is less and what is more. I would had paid less than normal because there is a tiny bit of chance on landing on its side.

Theta is a Greek letter. Here is all of the ones I know:

α β γ ε η θ ω π ξ

On the calculator it says 'error', but really there is no answer.

Yep. I mean that it does work for displaying the answer. Simply type a question on a scientific calculator, then see if this one shows the same thing.

Wait! This game is is a bit like the Chinese card game number 24 except the magic number doesn't change!

Puzzle 1 answer: I am confused. Don't get it.

$$opposite*1.5$$

or

$$adjacent*1.5$$

I think

Eating:

Only if they have no fat, sugar, or bacteria (bad ones). Too bad most cookies have fat.

Computer:

Depends on who you are.

Huh? What language are you writing in?

I love math (not easy questions).
