Question about Sharp EL-531VB Calculator

Hello,

No it does not have to be zero. Certain calculators display the content of the last screen, the one before it was turned off. As a rule you should make it your duty to press [ON/C] after turning calculator on, and before any new type of calculations.

If pressing the [ON/C] does not solve your problem, press the reset button on the back of the machine.

Hope it helps.

I do not know what make and model of calculator you have, but generally speaking, the M key stands for Memory key, When you press it it brings the content of the memory register on the display. But if you have not stored anything in memory (by entering a number then pressing M+) then the calculator displays the default value in memory, which is 0.

Press [SHIFT][MODE][6][4]:

When you select FIX (by pressing [SHIFT][MODE][6] ) on your calculator you can specify number of decimal places which are displayed (you can choose any number from 0 to 9).

Yes, you guessed right. Your configuration is set to Fix 0 AND scientific.

You can reset the calculator or you can change configuration (should be better to do the latter.)

I am describing the procedure for the CAS with OS version 2.1 But it should work for your calculator.

Turn calculator ON

Press The HOME (House iscon) button.

Press digit key 5 to open Settings and status.

In menu options, select [2:Settings]

Use the arrow (right) to open the submenu options and select [1:General]

The cursor should be on drop down box labeled Display Digits (You might see FIX 0, meaning 0 decimal digits, or 0 digits in mantissa of the number)

Use down arrow to open the number display format, and select Float 6 (an appropriate choice most of the time. If you want more digits, set Float 12)

Press [ENTER] or Click to validate your selection.

The drop down box will close.

Use the TAB button to move to another Configuration setting. Pressing the TAB twice will take you to Exponential format.

Use down arrow to unfold the Exponential format menu.

If you do not need Scientific Format, use Normal and validate.

Press TAB several times until cursor reaches OK.

At this point Press ENTER to save Configuration.

This should solve the problem.

As I said, this describes the procedure for OS version 2.1. Once you find out how to enter the setting screen, do as I described above, and do not forget to validate by getting the cursor on OK and validate.

Good luck.

The calculator has 10 memories (0 to 9)

To store a number (13) in memory 6 type 13 [STO] 6

To erase the content of memory 6 (M6) store 0 in int: 0 [STO] 6

To recall the content of memory location M7 press [RCL]7

To operate on the content of memory location M5 the syntax is [STO] [Op] 5, where [Op] is the operation symbol [+], [-],[x], [/] [y^x]

Ex: to raise the content of memory location 4 to the power of the displayed value, you press [STO][Y^x] 4

To clear all 10 memory locations

press [2nd][MEM][2nd][CLR WORK]

In short, although you do not have the keys you are accustomed to, you have a lot more. And please do not blame me if you feel disappointed.

Press the [SHIFT][MODE] to access the (SETUP) screen. -See the screen capture below. Press [7:Sci] to select the output display format to be Scientific.

You will then be prompted to key in a number between 0 and 9 to choose the number of decimal digits.

If you do not want fractions nor radicals set the default Input/Output format to LineIO.

To do so press [SHIFT][MODE][2:LineIO]. After that perform the steps given above to select Scientific format for the output.

Start by creating the data lists.

CREATE THE X-LIST

Using Tab to move from one line to the next, configure the calculator as seen on the next screen.

And the last line is at the bottom of the next screen capture

The statistical results will hence be displayed in the C[] column.

Use TAb to move focus to OK, and press ENTER.

Here they are.

You can recognize each statistical results, RegEq is y=mx+b. You also have m, b, r^2, and r. The residuals appear on the next row. By highlighting the cell with the {0.,0...0} you can display the hidden values

Here you have all you asked for. But you can go further by drawing the curve.

The regression equation is stored in function f1, so you have to draw the f1 function. .

DRAWING THE REGRESSION CURVE

Press the HOME button

Highlight and select [2:Graphs and Geometry]

At the bottom of the screen there is a command line with f2(x)=

Use the UpArrow to display the f1(x)= equation

Press ENTER to draw the function f1

I think I have to stop here. There is enough material to get you started.

I left for you the part where you draw the data points. read the user manual.

CREATE THE X-LIST

- Press Home.
- Use navigation pad to Highlight [3: Lists and Spreadsheets]
- Press Enter
- A list opens with cursor in Cell A1.
- Use UpArrow to move the cursor to the header of the list and give it a name, say X.
- Press Enter. Cursor moves to Cell A1
- Enter an X-value in each cell and press ENTER to move to next cell:
- Type 1, and press ENTER. Say Yes to overwrite message by pressing OK.
- Enter 2,3,4,5,6,7,8,9,10 (just a bogus sample).

- After typing 10 in cell A10, press ENTER to validate.
- Use the Navigation pad to move cursor to the head of the B column.
- Give it a name , say Y.
- Press ENTER, Cursor moves to cell B1.
- As for X-list, enter the Y values. Here is a sample (-2, -1, 0, 1,2,3,4,5,6,7). After you type value in B1, accept the overwrite message by pressing OK. Type the other values.
- Make sure that the X-List and Y-List have the same number of elements, otherwise you will have a dimension mismatch error.

- While the lidt is still displyed, prress the Menu key
- Highlight [4:Statistics]
- Use Right Arrow to unfold submenu list and select [1:Stat Calculations]
- Use right Arrow to unfold the submenu list and
- Select [3:Linear regression (mx+b)] or [4:linear regression (ax+b)]

Using Tab to move from one line to the next, configure the calculator as seen on the next screen.
