How can I use scientific notation on casio calculator?
Without knowing which model you're using, it's hard to say. However, you can find the owner's manual for all Casio calculators here: http://support.casio.com/en/manual/manual.php?cid=004 . Just click on "I agree" at the bottom to get the big list of calculators.
OK.
