Make sure you use the +/- key (located just to the right of the decimal point key) to enter a negative number, not the - key (to the right of the + key, used to subtract one value from another).

For example, press +/- 4 / +/- 3 = to divide -4 by -3 .

Make sure that you are using the negative button (-) and not the minus button next to the + sign. This would give you an error

I Finally figured it out after playing with it for almost 1/2 an hour!

Hit 2nd then Tax + (rate set) it will appear as 0.000 enter your tax rate... mine is 5% so I enter 5.0 then hit 2nd and Tax + (rate set again) And it will work!

It is glorious!!!

Page 1 for how to set date/time:

“RATE SET”: To set the date, time, and tax rate, set this switch at the “RATE SET” position.
Date:
• Enter in the order of month, day and year, then press to complete the entry.
• Use to separate month, day, and year.
• When is pressed, the number entered is evaluated and displayed as “date” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
date is restored.
Month: 1 - 12; day: 1 - 31; Year: 2000 - 2099 (in 4 digits) or 00 - 99 (in 2 digits)
Time:
• Enter in the order of hour, minutes, then press to complete the entry.
(There is no entry available for the seconds value. The clock starts at zero second.)

• Use to separate hour and minute values.
• When is pressed, the number entered is evaluated and displayed as “time” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
time is restored.

I can't get rid of the zero in front of the minus, add, multiply and devide sign. how do i get rid of it?


Are you entering any number before pressing the minus, add, multiply, or divide key? Those operations require two numbers; if you don't supply the first one then the calculator will supply the previous answer, which was zero.

For example, to add 2 and 3, press 2 + 3 = and you'll see 5. Now to add 4 to that, press + and the calculator will automatically supply the 5. Press 4 = and you'll see 9.

Just got a SHARP EL-531X, it won't do simple calculations with scientific notation, It keep saying


To enter the power of 10 with exponent use the Exp key followed by the exponent. If the exponent is negative, you must use the negation key (-) not the - key (for subtraction).
When you press the Exp key you do not type in the 10.
