Right. Stick with E. You KNOW that one is correct.

No, I think I'll just stick with the "E" for these kind of problems.

The 2.23 x 10^23 is correct. I just looked at my calculator and I don't have a ^ so scratch my explanation for that part. I have a yx on mine and I thought that's what you were referring to.

1.06 X 10^-21. The E button is the calculator's way of "x 10^something"; therefore, that answer is the good one. Punching the ^ button, gives you the number raised to some power. The E button raises 10 (not some number punched in) to a power that you add.
