some calculators do not compute ^ correctly.

I have a Casio fx-115MS, it shows 2^3^2=64.  It should be 512.  By the way, can you do the same for (...((x^x)^x)^...?  if you can, the result would be the same although they are two different problems. 

I used TI-89 calculator to compute (2^0.5)^(2^0.5)^(2^0.5)...and have not made it passed 2. 

Happy New Year to you.
