Get your Casio fx-570ES calculator...this works!

Hello again :) 

I have found that some of my students have difficulty when using this calculator for a variety of reasons. Ehm.. you might reset the calculator before using it for the first time. This is really important especially when you want to start making a new calculation.

Download this User Guide and Manual  . Senang cerita.. :) and seriously, this might help..

p/s oh yeah lastly,.. never leave a dead battery in the calculator. 

hehehe..
