• Displayed cell values show positive integers up to six digits, and negative
integers up to five digits (one digit used for negative sign). Exponential display
can use up to three significant digits.
• You can see the entire value assigned to a cell by using the cursor keys to
move the highlighting to the cell whose value you want to view.
• You can also display the sums of the terms (
"

n
or
"
b
n
) by turning on
