longer than 10 digits to be entered.  To perform this function, enter the number 
with the decimal point moved to the left.  Keep track of how many positions the 
decimal point moved.  Next touch the EEX button and enter the number of 
positions the decimal point was moved.  Touch the ENTER key to complete the

is entered, or comes as a solution, touching the CHS button will make it a 
positive.  Likewise, touching the CHS  button after a positive value is displayed 
on the screen will change its sign to a negative.
