Keying in Large Numbers 
Since the display cannot show more than 10 digits of a number, numbers greater 
than 9,999,999,999 cannot be entered into the display by keying in all the digits 
in the number. However, such numbers can be easily entered into the display if the 
number is expressed in a mathematical shorthand called “scientific...

Chain Calculations 
Whenever the answer has just been calculated and is therefore in the display, you 
can perform another operation with this number by simply keying in the second 
number and then pressing the operation key: you need not press \ 
to separate 
the second number from the first. This is because when a number is keyed in after
