2 Mastering the Calculator using the Sharp EL-531WH
A word about starting out
•Make sure you are in the correct mode selection and that all previous data is cleared. For e.g. To perform arithmetic operations pressTo clear all values press
To clear memory press
If your calculator has FIX or SCI or ENG on the display press If your calculator has RAD or GRAD on the display press until the letter DEG appears If all else fails press the RESET button on the back of your calculator (e.g. - after replacing batteries - to clear all memory content - when an abnormal condition occurs and all keys are inoperative). Mastering the Calculator using the Sharp EL-531WH 31. Addition and subtraction
1.1 To add numbers
Find thekey
(it is shown on the photograph of the calculator here).Example
To add 7 and 3, type
The display should read 10
To add 7 and 3.1, type
The display should read 10.1
addition keycancel last number keyBackspace key
4 Mastering the Calculator using the Sharp EL-531WH
Example
I want to find the total amount I earned in the past four weeks. If I earned $471, $575, $471 and $528, the key strokes would beThe display should read 2045.
1.2 Sometimes you make an error when typing in a number
If this happens use the key to cancel the last number typed and then type in the correct number and continue.Example
If you want to enter 3 + 4 but accidentally type
press to cancel the 5.Now type
Note that the key cancels just the last digit.
Example
If I want to add 471 and 575 but I typed
I can cancel 6 by typing and then typing
The display should read 1 046. Each time is used, the last digit is cancelled. Try practising cancelling with the key until you are comfortable with its use.1.3 The key is used when you want to delete a whole number
Example
If you typed:
471 + 566
but you wanted 471 + 576 Mastering the Calculator using the Sharp EL-531WH 5 press the key to navigate. Note the 566 disappears. Press the key again, the + sign becomes static. Now type in 576 then .The display should read 1 047.
Note: For the EL-531GH calculator, use the to cancel the last number and use the to delete a whole number and then retype the new number.1.4 When you want to edit, use the keys to move the cursor to the left
or rightExample
If you typed 471 + 568 +, but you wanted 567
Press the until the number 8 begins to flash [press to undo] Press and 8" disappears. Now type in 7" and press until the + sign stops flashing.1.5 To subtract numbers
Find the key (it is shown on the photograph of the calculator following).Example
To subtract 35 from 257, type
The display should read 222
6 Mastering the Calculator using the Sharp EL-531WH
Example

Sometimes you may have a sum like this:
-7 + 4You can use the key.
The key strokes are
The display should read -3.
You could also use the keystrokes
In this case the calculator recognises (the - as a negative (not recommended to do it this way)). plus minus keysubtraction key Mastering the Calculator using the Sharp EL-531WH 72. Multiplication and division
2.1 To multiply numbers
Find the key (it is shown on the photograph of your calculator here).Example
To multiply 7 and 3, type
The display should read 21
To find 753 492, type
The display should read 370 476
key for divisionkey for multiplication8 Mastering the Calculator using the Sharp EL-531WH
2.2 To divide numbers
Find the key (it is shown on the photograph of the calculator)Example
To divide 35 by 7, type
The display should read 5
To divide 7 905 by 85, type
The display should read 93
To divide 60 by 5 and then by 4 type
The display should read 3.
2.3 Combining multiplication and division
Example
If the question is
then it is really 27 (7 x 4).Try it.
The display should read 0.964285714

Mastering the Calculator using the Sharp EL-531WH 93. Brackets and order of calculation
Find the set of bracket keys on your calculator.
The EL-531WH allows you to many sets of brackets.
Example
Do the calculation 471 - (93 + 11 + 2) on the calculator.The keystrokes required are
The display should read 365.
Sometimes in calculations you will see other grouping symbols, for example, { } (called braces), [ ] (called square brackets). Misplaced or omitted brackets can give an incorrect result due to the priorities given to operation by the calculator.LH bracket keyRH bracket key
10 Mastering the Calculator using the Sharp EL-531WH
Example
While 5 × (3 + 4) will give 35
5 × 3 + 4 is the equivalent to
(5 × 3) + 4 and will give a result of 19.Try these examples:
Exercise 1
(a) 25 + (7 + 2 - 4) (b) 18 (3 + 7) [a multiplication sign is understood 18 (3 + 7)] (c) 4 + 5 [2 (3 + 7)] [to use two sets of brackets just press the same button; this calculator can take up to 6 sets of brackets] (d)Answers: 30; 180; 104; 1

Mastering the Calculator using the Sharp EL-531WH 114. Powers
4.1 Squaring and higher powers
6 2 means 6 6. You can use the square key to do this calculation. (It is shown on the photograph of your calculator here.) Press the display should read 36.Or you can use the power key on your calculator.
Find the y
x key on your calculator. square key square root key power key12 Mastering the Calculator using the Sharp EL-531WH
Example
To square 6,
that is, find 6 2 , typeThe display should read 36
[The first number you put in is the 6. This is the y and the second number you put in (2) is x.That is why it is called the y
x key.]To find 27
3 the required key strokes are or and the display should read 19683. If you have learnt your multiplication tables you will already know the squares of the whole numbers from 1 to 12 and thus be able to complete much of the following table.Exercise 2
Use your calculator to find the squares of the whole numbers from 13 to 25 and any other squares you are unsure of. 1 2 = 111 2 =21 2 2 2 = 412 2 =22 2 3 2 = 913 2 =23 2 = 529 4 2 =14 2 =24 2 = 576 5 2 =15 2 =25 2 = 625 6 2 =16 2 7 2 =17 2 8 2 =18 2 9 2 =19 2 10 2 20 2 Mastering the Calculator using the Sharp EL-531WH 13Exercise 3
You can use this key for other powers as well. Try these examples (a) 7 4 (b) 8 10 (c) (0.4) 6 (you do not have to type the brackets in) (d) (-7) 6 (you do not need to type the brackets in if you use the key) (e) 5 0.4 (f) 5 -4Answers:
(a) 2401 (b) 1073741824 (c) 4.096 10 -3 or 0.004096 (you move the decimal 3 places to the left) (d) 117649 (e) 1.903653939 (f) 0.00164.2 Square root
Finding the square root of a number 'undoes' or 'neutralises' the squaring of the number and vice versa. The symbol for square root is (This is called the radical sign)The square root of 36 is written as
Now because 6
2 = 36, . Find the square root key on your calculator and typeThe display will read 6.

You should have said 9 because 9
2 = 81 (Check your calculator)Exercise 4
Try these by looking at the table of squares you completed on the previous page and then check your answers on your calculatorThe answers are 4, 12, 10, 21, 7, 13, 11, 19.
Let"s now check that taking the square root neutralises squaring.Try this on your calculator.
Find the square root of 3 squared that is,
The key strokes required are
The display should read 3
Because squaring and taking square roots are inverse operations, the order of the operatons can be reversed and the number is unaffected. So the square, of the square root of 3, should also equal 3 Try it on your calculator. The key strokes required are (a) =(a) = (a) =(a) = (a) =(a) = (a) =(a) = 1649144169
