To add INT and PRICE after executing the bond E function, press +~}. In this case, ~ is used to enter the second argument for the + operation. After executing +~}, the total price (INT + PRICE) will be displayed. LAST X will be unchanged, but the original PRICE will be found in the Y-register. One can also do +d} to get the total price, with the only difference being that the original PRICE would then be in the T-register. Parentheses Calculations In ALG mode, parentheses can be used in calculations to change the order in which operations are evaluated. When there are pending open parentheses, the ( ) status indicator will be shown in the display. As open parentheses are closed, the expression contained within the parentheses is evaluated. The final result of a calculation will be displayed when you press the ³ key, and then any pending parentheses will be closed. You can't use more than 13 pending (opened) parentheses at the same time. 8 (5 − 1) Keying 8 ÷ 5 - 1 will calculate 8 ÷ 5 first and then the result (1.6) will have 1 subtracted from it (resulting in 0.6).
