The calculator has ten memory variables for repeated use : A, B, and . You can store a real C, X, Y, M, X1, X2, PROG1 PROG2 number in variables and an expression in A, B, C, X, Y, M, X1, X2 and . See Example 5. PROG1 PROG2 * [ P/V RCL ] recalls all variables. * [ SAVE ] lets you store values to variables. * [ 2nd ] [ RECALL ] recalls the value of variable. * [ 2nd ] [ CL-VAR ] clears all variables except PROG1, PROG2. * [ 2nd ] [ CL-PROG ] clears the contents of PROG1, PROG2.

Mode 0 - MAIN Arithmetic Calculations Arithmetic operations are performed by pressing the keys in the same sequence as in the expression. See Example 6. For negative values, press [ ( ) ] before entering the value. See − Example 7. For mixed arithmetic operations, multiplication and division are given priority over addition and subtraction. See Example 8. 10 -9 Results greater than 10 or less than 10 are displayed in exponential form. See Example 9. Display formats
