i want to know how to calculate in calculator "casio fx-991ms" fx-991ms" to calculate log value

In any scientific calculator log2(n) can be calculated with either ln or log function as
follows

Log2(n)= ln(n) / ln(2)

Or

Log2(n)=log(n) / log(2)

both will give nearly the same answers

how do I calculate the mod function in my casio fx 100ms model

It seemed there is no Modulo function in fx-100MS. But Mod is just the remainder of a division operator.

So if you have A mod B = C, divide A by B, subract the remaining whole number, and multiply it by B to get C.

Example:

7 mod 4 = 3

In the Calculator:

7 / 4 = 1.75, then 1.75 - 1 = 0.75. Then 0.75 x 4 = 3

My calculator answers in scientific notation. How do you reset your casio fx-300Ms (S-V.P.A.M)?

Thank You so very much, this solution fixed my problem.

how to solve a quadratic formula using a casio fx-300 MS

Hello,

The calculator does not have a solve program, but you can still use it to solve the quadratic equation with a little effort. If you know the therory skip toward the end.

Let aX^2+bX+C=0

1. First calculate the discriminant usually called Delta and given by

Delta =b^2 -4*a*c store the value in the variable D

If Delta is positive you have two roots X1 and X2 given by

X1=(-b+square root of Delta)/(2*a)

X2=(-b- square root of Delta)/(2*a)

If Delta is equal to 0, X1=X2=-b/(2*a)

If Delta i negative, no real solutions exist

You only solve if Delta is positive or equal to 0.

Putting in the values of a, b, and c

value of a (put you number) [SHIFT][STO] A

value of b (put your value) [SHIFT][STO] B

value of c (put you value) [SHIF][STO] C

[ALPHA] B [X^2] -4[x][ALPHA] A [x][ALPHA] C [=]

Value of delta is displayed. If it is positive, you store its square root in D

[Square root] [ANS] [SHIFT][STO] D ;

Calculate 1/(2*a) and store in variable F

1./(2[x] ALPHA A) [SHIFT][STO] F

To obtain X1

[ALPHA] F [x] ( (-) ALPHA B + ALPHA D ) [=]

To obtain X2

[ALPHA] F [x] ( (-) ALPHA B - ALPHA D ) [=]

Be careful: the (-) is the change sign not the regular minus sign.

Hope it helps.

PLEASE HOW DO I CHANGE MY CASIO FX-82MS CALCULATOR FROM ROUNDING UP ANSWERS.

Hello,

Use the FIX display format and set the number of decimal digits to be displayed to be 2 o 3 or more depending on your needs. Instructions are on screen capture below. Hope it helps.

how to get a Casio out of rounding mode

Press the MODE key a certain number of times, until you reach a screen that displays FIX SCI NORM and numbers 1, 2, and 3 under them. Press 1 key to select the FIX display format, then enter a number between 0 and 9 to set the number of decimal digits you want to keep in your result. In your case the calculator is already rounding so you should select a reasonable number of digits say 2 to 3.

MODE (a certain number of times ....) 1 (FIX) 3 will keep three decimal digits in the results.

How can I get my calculator out of scientific notation mode? It is a casio fx 300ms

Please press the Mode button on your calculator repeatedly till you get the following screen

Fix Sci Norm

1 2 3

Press 3 from your keypad and the screen will change to

Norm 1~2?

Press 1 from your keypad and your calculator will be normal again i.e out of scientific notation mode.

how to find ln (inverse log function) in casio calculater

The inverse function of the natural log (ln) is the exponential function (e^x). They share the same physical key. One is direct access key and the other is the shifted one: You have to press [SHIFT] to enable it.

how to convert to binary using casio fx-350MS?

Hello,

In the FX300Ms manual, the same for the FX350MS, there is no way to use base-n (binary, octal, hexadecimal) calculations.

Sorry.
