Changing a mode

Pressing [MODE] can enter mode menus. You can choose one of six operating modes, including "0)MAIN", "1)STAT", "2)Base-n", "3)CPLX", "4)VLE", "5)QE".

Give “ 2)Base-n ” as an example :

Method 1: Scroll through the menus using [ · or [ ] until "2)Base-n" is shown, then enter the desired mode by pressing [ENTER].

Method 2: Key in directly the number of the mode, [2], to enter the mode immediately.

Selecting an item from display menus

Many functions and settings are available on menus. A menu is a list of options displayed across the entry line.

Give “ Pressing [ DRG ] key displays the menu for choosing the angle setting under MAIN mode ” as an example :

Method : Press [ DRG ] to display the menu, and then move the cursor [ · or [] to an item you want. Press [ ENTER ] while the item is underlined.

For menu items followed by an argument value, enter the argument value while the item is underlined. The item and the argument value are displayed in the previous screen.

Using “ 2nd ” keys

When you press [2nd], the “2nd” indicator shown in the display is to tell you that you will be selecting the second function of the next key you press. If you press [2nd] by mistake, simply press [2nd] again to remove the “2nd” indicator.

Cursor

Pressing [ ] or [ ] key can move the cursor to the left or the right. Hold down any of those keys to move the cursor at high speed.

Pressing [▲] or [▼] can scroll the display up or down while there are previous entries hidden the display. You can reuse or edit a previous entry when it is on the entry line.

Making corrections during input

To delete a character at the cursor, make the character underlined by using or [] to move the cursor, and then press [DEL] to delete the character. Besides, holding down [DEL] can deletes all characters to the right; then,

deletes 1 character to the left of the cursor each time you press [ DEL ].

To replace a character, make the character underlined by using [] or [] to move the cursor, and then enter a new entry to replace the character.

To insert a character, move the cursor to the position of the character where you want to insert, it will be inserted in the front of the character after pressing [2nd] [INS] and entering a new character.

(Note): The blinking cursor “ ” means the calculator is in insert mode. On the contrary, the blinking cursor is displayed as “_” and it means the calculator is in overwrite mode.

To clear all characters, clear all input character by [CL] key.

Replay function

• This function stores the latest operation executed. After execution is complete, pressing [▲] or [▼] key will display the operation from the beginning or the end. You can continue moving the cursor by [▶] or [▲] 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 228 characters for SRP-280 or 320 characters for SRP-285. After execution is complete or during entering, you can press either [ ] [ ] to display previous input steps and edit values or commands for subsequent execution. See Example 2.

(Note): The replay function isn't cleared even when [ CL ] is pressed or power is turned off, so contents can be recalled even after [ CL ] is pressed. However, replay function is cleared when mode or operation is switched.

Error position display function

• When a mathematically illegal calculation is performed, error position display function will tell you with the cursor where the error is. Press [▶] or [▲] to move the cursor and then give it a correct entry. You can also clear an error by pressing [CL] and then re-entered the values and expression from the beginning. See Example 3.

• The calculator has eight memory variables for repeated use: A, B, C, X, Y, X1, X2, PROG. You can store a real number in variables A, B, C, X, Y, X1, X2 and an expression in PROG. See Example 5.

• [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 PROG.
• [2nd] [CL-PROG] clears the contents of PROG.

Order of operations

Each calculation is performed in the following order of precedence :

1) Expression inside parentheses.
2) Coordinates transformation, and Type B functions which are required pressing the function key before entering, for example, sin, cos, tan, sin -1 , ^-1 , ^-1 , sinh, cosh, tanh, sinh -1 , ^-1 , ^-1 , log, In, 10^× , e ^x , , NEG, NOT, X'( ), Y'( ).

3) Type A functions which are required entering values before pressing the function key, for example, X^2 , “, !, X^-1 , %, r, g.
4) Exponentiation (), [x]x
5) Fractions
6) Abbreviated multiplication format in front of variables, , RAND.
7) (-)
8) Abbreviated multiplication format in front of Type B functions 2 3 , Alog2, etc.
9) nPr, nCr
10) x, ÷
11) +, -
12) AND, NAND
13) OR, XOR, XNOR
14) Conversion (A b/c d/e, F D, DMS)

• When functions with the same priority are used in series, execution is performed from right to left.

$$ e ^ {x} \ln 1 2 0 \rightarrow e ^ {x} \left{\ln (1 2 0) \right} $$

otherwise, execution is from left to right.

• Compound functions are executed from right to left.
• Anything contained within parentheses receives the highest priority.

Hexadecimal base ():0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F

• Pressing [ ] can use block function to display a result in octal or binary base which exceeds 8 digits. The system is designed to display up to 4 blocks. See Example 40.

4-2 Negative expressions

• In binary, octal, and hexadecimal bases, the calculator represents negative numbers using complement notation. The complement is the result of subtracting that number from 1000000000 in that number's base by pressing [NEG] key in non-decimal bases. See Example 41.

4-3 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 42.

4-4 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). See Example43.

5 Mode 3 - CPLX

• Complex mode enables you to add, subtract, multiply, and divide complex numbers. See Example 44. The results of a complex operation are displayed as follow:

Re Realvalue

Im

Imaginary value

ab Absolutevalue

ar

Argument value

6 Mode 4 - VLE

Variable linear equations (VLE) mode can solve a set of simultaneous equations with two unknowns as follows :

$$ a x + b y = c $$

dx + ey = f , where x and y are unknown.

• In VLE mode, you just enter each coefficient (a, b, c, d, e, f) in the correct order, and the calculator automatically solves for x, y . See Example 45.

7 Mode 5 - QE

Quadratic equations (QE) mode can solve a equations as follows :

a x^2 + b x + c = 0 , where x is unknown.

• In QE mode, you just enter each coefficient (a, b, c) in the correct order, and the calculator automatically solves for all x values. See Example 46.
