The stack is a series of storage locations for numbers and other

objects. In general, you will use the HP 48 by entering numbers and

other objects onto the stack, then executing commands that operate

on the data.

Using the Stack for Calculations

You ordinarily do calculations by entering objects onto the stack

and then executing the appropriate functions and commands. The

fundamental concepts of stack operations are these;

■ A command that requires arguments (objects the command acts

upon) takes its arguments from the stack. Therefore, the arguments

must be present before you execute the command.

■ The arguments for a command are removed from the stack when the

command is executed,

■ Results are returned to the stack so that you can see them and use

them in other operations.

Making Calculations

When you execute a command, any arguments in the command

line are automatically put onto the stack before the command is

executed. This means you don’t always have to press fENTER) to put

the arguments on the stack—you can leave one or more arguments in

the command line when you execute the command. (You should still

think of the arguments as being on the stack, though.)
