To calculate modulo with the FX-115MS calculator, follow these steps:

e.g.: 9%4=1

9 (minus) 9 (divide) 4 (times) 4 =

so, 9-9/4*4 will yield the correct answer of 1

How to calculate 7^35mod561 in calci fx-991ms?



I don't have that calculator handy, but I imagine the problem is that 7^35 is an awful big number and the calculator would put it in scientific notation. So can we rearrange the question so that we can do it on the calculator.

The 7 is already prime, so we can't do much with that.

However, we can divide up the 35 into its factors of 7 and 5.

Thus, 7^35 mod 561 = (7^5)^7 mod 561

This becomes 7^5 mod 561 ^ 7 mod 561
16807 mod 35 ^7 mod 561
538 ^ 7 mod 561

Can find mod


I am not sure I understand what you want.
123 mod 3=0
123 mod 391 =123
391 mod 123 =22
I cannot say if the calculator can do modulo calculations. the only manual I could unearth is in the language of tomorrow (Chinese).

How to calculate mode with caso fx-991ES


MOD simply calculates the remainder that is left over after dividing by the MOD parameter.
For example, 10MOD7 = 3 since you can only divide 7 into 10 once, leaving a remainder of 3.
For larger numbers, eg 389487MOD31 you start by dividing 389487 by 31, which gives 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD calculation has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculators working capacity.
An alternative method is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

How can I find :11^27mod 29 using my CASIO fx-99IES


11^27 = 13,109,994,191,499,930,367,061,460,371 which is 29 digits long.

You can get this result from the Windows calculator (scientific view) by entering 11 and then pressing x^y 27 = . Then use Mod 29 = to get the result, which is 8.

Unfortunately the Casio fx-991ms (as with most other calculators) doesn't have nearly enough digits to cope with this type of calculation. You therefore need to split the calculation down into more manageable chunks, as follows, which works on most calculators:

First calculate 11^3 = 1,331 and work out Mod 29, which is 1,331 - 45×29 = 26.
Then calculate 26^3 = 17,576 and work out Mod 29, which is 17,576 - 606×29 = 2.
Finally calculate 2^3 = 8. Since this is less than 29, it is also the final answer as confirmed above.

This method can be used with any power number that can be factorised into numbers that don't cause the available digits of the display to overflow. In this case 27 = 3×3×3 so each step involves cubing the previous answer.

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

A mod B in Casio fx-115MS How to get an m mod n (ie to calculate modulo of a number)


It's a bit convoluted, and it only works for integers, but here's one way. Press MODE 4 to switch to BASE-N (integer) mode. If the screen doesn't read "Dec" then press the x^2 key. Now, to calculate m mod n, calculate m-m/n*n. No shortcuts, no rearranging. That's m minus m divided by n times n. You have to enter both numbers twice, but you will get the modulus.

Press MODE 1 to return to your previously scheduled calculations.

How to calculate 24124 mod 19937 in casio fx-991Ms calculator


The MOD function simply returns the remainder that is left over after dividing the two numbers.

In this case, its possible to see quite easily that only 1×19937 can be taken from 24124 before the remainder is less than 19937. The MOD function is therefore the same as 24124 - 19937 = 4187.

In cases that are less obvious, do the division, ie 24124 ÷ 19937 = 1.210011536[34]
[The last two digits are hidden on the display but still used in subsequent calculations].
Then obtain the fractional part by subtracting 1 to give 0.210011536[34]. Then multiply the answer by 19937 to give 4187. Assuming that you haven't cleared the screen between each section of the calculation, the screen will show "Ans×19937 [=] 4187".
