# Parentheses Calculations - HP 12C Platinum User Manual

Financial calculator.

The stack diagrams showing the output for the Calendar and Financial functions on
page 237 are the same for ALG as RPN mode. 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.
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).
