Parentheses calculations • Operation inside parentheses are always executed fi rst. The cal- culator can use up to 15 levels of consecutive parentheses in a single calculation. See Example 8. Percentage calculation • [ 2nd ] [ % ] divides the number in the display by 100. You can use this key sequence to calculate percentages, add-ons, discounts, and percentages ratios. See Example 9~10. Display formats This calculator has the following four display notation mode for the display value.
