If you press the setup key then 1 under FSE it will say TAB (0-9)? enter the amount of decimal places you want and it will change that for you.

SOURCE: how do I use sharp EL 531W to solve quadratic equations?

Hello,
This calculator does not have a program to which you give the equation, and which returns the solutions. Sorry. You have to use the formulas you learned.
Let the equation be ax^2 +bx+c=0
You compute the discriminant Callit disc.
disc= (b^2-4*a*c)
1. If discriminant is larger than zero you have two solutions. Let us call them x1 and x2.
Then x1=(-b+square root of disc)/(2*a)
and x2= (-b-square root of disc)/(2*a)

2. If disc=0 , square root of disc =0 and x1=x2=-b/(2*a)
3. If disc is negative, there are no real solutions.

To find the solutions you replace a, b, and c by their numerical values, to calculate disc, its square root, and calculate X1 and X2.

Hope it helps.

From the manual:

SETTING THE NUMBER OF DECIMAL DIGITS
Numbers of decimal digits of calculation results can be specified by pressing [C-CE] twice, then press [C-CE]and [M+] simultaneously.
The decimal digit assignment will appear as “F” (for “floating point”), “2” or “0” on the LCD. (The default is “F”.)
Press and hold [C-CE] and [M+] until the symbol changes.

How do I change a percentage to a fraction

How to convert percent to fraction

  1. Divide the percent by 100 to get decimal number.
  2. Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
  3. Calculate the factor (f) for making the decimal number an integer: f = 10 to power d
    Example:
    f = 10 power 2 = 100
  4. Multiply and divide the decimal number x by the factor f: x * f / f = y / f
    Example:
    2.56 * 100 / 100 = 256 / 100
  5. Find the greatest common divisor (gcd) of the fraction. Example:
    gcd(256,100) = 4
  6. Reduce the fraction by dividing the numerator and denominator by the gcd value: Example:
    256 / 100 = (256/4) / (100/4) = 64/25
Example One percent is equal to one hundredth:
1% = 1/100
So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.
For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:
56% = 56/100 = 14/25

Casio fx-82ms calculator does not give me an answer when i use the percentage button . example if i type 0.25/ 100% i get 0.25 instead of the right answer 25


Here is a sample of the percentage calculations that the calculator can perform. You will not see among them the conversion from decimals to percentages.
To convert from decimals to percents move the decimal mark 2 places to the right and append the % sign.
To convert from percents to decimals, move the decimal mark 2 places to the left.

I cant figure out what is the shift key on my calculator. I have a Sharp EL-531W. I tried the 2NDF key and its not coming out right.


Regardless, that is the markings on the SHIFT key on Sharp Calculators. The 2ndF key accesses the functions that are marked on the face of the calculator, not on the top of the keys.

I have a Sharp EL-531W.All keys work except for sin cos tan hyp.


No solution, but I have the exact same problem with a Sharp EL-531W calculator. Doesn't matter whether mode is degrees, radians, etc., and resetting with button in back has no effect.

Calculating Percent savings


Since I don't use the percent sign. Here is instead a MUCH easier way. Divide the price you bought it for (289) by the original price (648). This gives you the percentage that 289 is with respect to 648 if you just read off the first two decimal places. When you divide one number by another it will tell you how many times they 'fit' for the purpose of explaining it. That is also essentially what a percentage is out of 100 parts. so when you divide one number by another, you will get a decimal answer, just multiply it by 100 (or just take the first two decimals) and that is percent saved (percent different). Note that if the first value is LARGER than the second, you will have a percentage of over 100%.

I have a Sharp EL-1801P III. I want to make it so that when I type numbers in and his add it automatically puts the decimal in for me. For example if I typed in 3596 it would make it 35.96. Is this...


Your calculator has a decimal counter (top center of calculator starting with the letter F654321A) for lack of a better name for it. Anyway mine is set at A. It puts the decimal in for me. I hope this helps you. if you haven't figured it out by now.
