# SHARP EL-735S (EL-738) SUMMARY of FUNCTIONS for TEACHERS

SHARP EL-738(735s) SUMMARY OF FUNCTIONS FOR TEACHERS

Hi Everyone,

I have put together a summary of the key sequences for the above calculator which will achieve what we currently teach in both FNSACCT608A (FMP) and FNSACCT609A (FMA).

What was thought was going to be a nice easy transfer for a calculator that supposedly performed the same functions (and then some), has turned out to be a nightmare in the class room. It now takes twice as long to teach the calculator sequence as we have to deal with two entirely separate processes. Hopefully this is just a temporary setback until we, ourselves, become used to the new calculator. An example of this is when using the EL-735 to clear the DCF registers (PV, i, n, FV) you would key; 2ndF, CA. This is still the same process with the EL-738 except the CA key is no longer the red button and for those of us used to the process of ‘orange’ key, ‘red’ key – on the EL-738 you end up turning the calculator OFF! Annoying, but something to get used to.

Having said this, I do think the new calculator has some advantages over the old one – particularly the fact that it has a larger screen and larger buttons (great for those of us with failing eyesight).

TO SET THE DECIMAL POINT (TAB)

The (EL-738) has factory defaults. Two of these defaults are the decimal point (set to [2] two decimal places), and the date format. These can be changed using the SETUP

key.

Note that if you use; 2ndF, M-CLR, 0 , 0 , this will reset the calculator to the factory defaults and any tab or date settings will need to be re-entered.

To set a fixed number of decimal points; SETUP, 0 , 0 , and then select the number of decimal points required between 0 and 9.

Note that the number of decimal points only affects what is shown on the display. Internal calculations still use a mantissa of up to 14 digits. See also the Modify function MDF on page 63. After a calculation, you may observe any number of decimal places by using SETUP , 0 , 0 , and then selecting the number of decimal points required between 0 and 9.

To set a floating decimal point (only used in Scientific mode); SETUP, 0 , 1 , and then select the number of decimal points required between 0 and 9.

TO SET THE DATE FORMAT p.10 & p.52

SETUP, 3 , 1 , for Australian format. Default is the US format.

To enter a date; DATE,dd ,mm, yyyy,ENT

MODE p.10

The default mode is 0 ; Normal/Financial mode.

To enter Statistical mode; MODE , 1 ,and then choose either 0 for single variable or, 1 for Linear (2) variables.

MEMORY p.14

The EL-738 has a number of temporarymemories in addition to the Independent memory M. Refer p.15. The temporary memories are useful for storing numbers somewhere whilst other calculations are being performed.

To store in a temporary memory; (value), STO ,and then select one of the temporary memories A- H , or X- Z.

To recall a temporary memory value; RCL ,and then the memory letter A- Hor X- Z .

The temporary memories retain their contents when the calculator is switched off.

The Independent memory Mcan be added to, M+or subtracted from, 2ndF, M- in the accustomed way. However, there is no RM. This is achieved as above by using, RCL , M+. To clear this memory; ON/C, STO , M+.

TIME VALUE OF MONEY (TVM) p.22

Compound Interest:

The EL-738 now allows for variation between the number of payments per year 2ndF,P/Y ,and the number of compounding periods per year 2ndF, P/Y, ▼. They do not need to be the same. The default is that the number of compounding periods per year is automatically set to the same value as P/Y. This is what we currently do with the EL-735 when we enter adjusted values for n and i (note that the i key on the old calculator is now the I/Y key on the new calculator) and the procedure will not change other than now using the I/Y key.

If you wish to experiment with the new feature:

-ensure the number of payments per year is set first, then set the number of compounding periods per year, then clear the display. For example,

2ndF, CA,2ndF, P/Y, (value),ENT , ▼ , (value), ENT , ON/C

- enter variables and compute missing variable. Note, Interest rate is entered as an Annual rate I/Y .

Refer examples on p.23– p.27 of manual.

AMORTISATION (AMRT) p.33

Enter TVM variables.

Compute PMT if required.

Finding amounts between periods;

AMRT, then P1 payment, ENT , ▼ , then P2 payment, ENT .

▼ = Balance at end of P2 payment.

▼ = Principle reduced at end of P2 payment.

▼ = Interest paid at end of P2 payment.

Finding amount for nth period;

Use the same procedure as above but use the same value for P1 and P2.

DISCOUNTED CASH FLOW ANALYSIS (DCF) p.37

To clear Cash Flow registers;

CFi, 2ndF, CA , ON/C .

To enter data;

Enter Cash Flow amount, DATA .

For repeated Cash Flows, enter Cash Flow amount, (x,y) , enter number of repeated amounts (frequency), DATA .

To correct a value before pressing DATA , press ON/C to delete the value and then enter the correct value.

To confirm data;

CFi, then use ▲or ▼ to display data (amount), then frequency.

To edit data;

Display the data item to modify using ▲or ▼, enter new value, then DATA .

To delete data;

Display the data item to modify using ▲or ▼, then 2ndF, CLR-D .

To insert data;

Display the data item that will come immediately after the new item, then 2ndF, INS-D , enter new amount (and frequency if required), DATA .

NET PRESENT VALUE (NPV) and INTERNAL RATE OF RETURN (IRR) p.40

NPV

Enter Cash Flow data, 2ndF, CASH , enter discount rate, ENT, then ▼ to select NPV, then COMP.

IRR

Repeat for NPV, then ▼ to select Rate (I/Y), then COMP.

CONVERSION BETWEEN ANNUAL PERCENTAGE RATE (APR) AND

EFFECTIVE RATE (EFF) p.51

Enter number of compounding periods per year, (x,y) , (interest rate), then either;

2ndF, →EFF to convert from an Annual % rate to an Effective rate, or

2ndF, →APR to convert from an Effective rate to an Annual % rate,

STATISTICAL FUNCTIONS p.64

To enter STAT mode;

MODE, select , 1 ,and then choose either 0 for single variable or, 1 for Linear (2) variables.

To clear any previous data entered;

2ndF, CA

Single Variable data:

Enter value, then DATA .

To enter multiples of the same value;

Enter value, (x,y) , number of times (frequency), DATA .

_

To compute Mean (x), Standard Deviation (sx) or (σx);

RCL, then the appropriate key ( x, sx, or σx ).

Two Variable data:

Enter ‘x’ value, (x,y) , ‘y’ value, DATA .

To enter multiples of the same value;

Enter ‘x’ value, (x,y) , ‘y’ value, (x,y) , number of times (frequency), DATA .

_ _

To compute (x), (y), (σx), (σy) and (r);

RCL, then the appropriate key ( x, sx, σx, y, sy, σy , or r,).

I hope this helps! If you get stuck, the examples in the manual are fairly straightforward.

If I have left anything out that is relevant to teaching the above Units of Competency, please let me know.

Kind regards,
