] to edit it. To delete a digit, press [ DEL ]. ( or, in overwrite mode, just type over the digit). See Example 1. The replay function can keep input digits up to 254 characters for SRP-285II. After execution is complete or during entering, you can press either [ ] or [ ] to display previous input steps and edit values or commands for subsequent execution. -
Page 7: Order Of Operations
The calculator has ten memory variables for repeated use : A, B, C, X, Y, X1, X2, PROG1 and PROG2 . You can store a real number in variables A, B, C, X, Y, X1, X2 and an expression in PROG1 and PROG2 . -

See Example 14. Parentheses Calculation Operations inside parentheses are always executed first. SRP-285II can use up to 13 levels of consecutive parentheses in a single calculation. See Example 15. Closed parentheses occurring immediately before operation of the ] key may be omitted, no matter how many are required. -
Page 12: Percentage Calculation
A multiplication sign " x " occurring immediately before an open parenthesis can omitted. See Example 17. (Note) : The calculator can auto-correct abbreviated multiplication in front of all functions, except memory variables, left parenthesis, type B functions. Henceforth, abbreviated type will not be used in this manual. See Example 18. -
Page 13: Angle Unit Conversion
To enter a mixed number, enter the integer part, press [ A enter the numerator, press [ A ], and enter the denominator ; To enter an improper fraction, enter the numerator, press [ A ], and enter the denominator. See Example 28. During a fraction calculation, if the figure is reducible, a figure is reduced to the lowest terms after pressing a function command key ( [ + ], [ –... -

Page 20: Basic Arithmetic Operations For Bases
Basic arithmetic operations for bases The unit enables you to calculate in number base other than decimal. The calculator can add, subtract, multiply, and divide binary, octal, and hexadecimal numbers. See Example 61. Logical operation Logical operations are performed through logical products (AND), negative logical (NAND), logical sums (OR), exclusive logical sums (XOR), negation (NOT), and negation of exclusive logical sums (XNOR).
