Example: Calculate 3.42, first in RPN mode and then in ALG mode. Keys: 9 9 Display: Description: Enter RPN mode (if necessary) Enter the number Press the square operator Switch to ALG mode Enter the square operation Insert the number between the parentheses Press the Enter key to see the result In the example, the square operator is shown on the key as but displays as SQ(). There are several single argument operators that display differently in ALG mode than they appear on the keyboard (and differently than they appear in RPN mode as well). These operations are listed in the table below. Key In RPN,RPN Program X2 √x ex 10x 1/x In ALG, Equation, ALG Program SQ() SQRT() EXP() ALOG() INV() Two Argument or Binary Operations Two argument operations, such as and x, are also entered differently depending on the mode though the differences are similar to the case for single argument operators. In RPN mode, the first number is entered, then the second number is placed in the x-register and the two argument operation is invoked. In ALG mode, there are two cases, one using traditional infix notation and another taking a more function-oriented approach. The following examples illustrate the differences. Getting Started 1-19
