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 a mod b, calculate a-a/b*b. No shortcuts, no rearranging. That's a minus a divided by b times b. 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 5^(-1)mod 792

I am sorry, but I was under the impression that the modulo operation involves integer divisions only. This means it involves only integers. However 5^(-1) is a rational number that is not an integer. And then I could be wrong.
As to doing modulo operations with this calculator, well you can't. Sorry again.

### Can anyone help me to solve this problem? 11^23 mod 187

One way to do this is to simplify it piece by piece. We know 11^23 = 11 * 11 * 11 * 11^20, and we know
that 11 * 11 * 11 = 1331 in to find this modulo 187 we look at 1331/187 which is > 7, so we can take 1331 - 7 * 187
which is 22. So 11^3 mod 187 is 22. we can simplify 11 ^23 = ( 11^3 ) * 7 * 11^2 because we know 11^3 = 22
we can write this as 22 * 7 * 11^2. and 11^2 mod 187 is 121 so now have a number to modulo.
11*7*121 mod 187 = 9317 mod 187 this is 88. Hope this helps you understand simplifying.

### How to do modulo operation in casio fx991ms

The fx-115ES does not have a modulo operator. However, it is possible to compute the remainder using integer arithmetic. Press MODE 4 to shift into integer mode. Then calculate A modulo B as
A - B * (A / B). For example, to calculate 41 modulo 6, press
4 1 - 6 * ( 4 1 / 6 ) =
and get 5.

Press MODE 1 to return to real arithmetic.

### How to get mod on it

If you are thinkink of the modulo function, usually shortened to mod(, I am sorry to say it but that function does not exist on the calculator.
However, there is MODE button that one uses to set the operation mode of the calculator.
You have three principal mode setting
COMP: the general computational mode
SD: a statistics mode to calculate Standard Deviations
REG: to perform REGression analyses on statitical data.

Once you have chosen the preferred calculator mode (COMP, SD, or REG) other choices (dependent on the main calculator mode) will be available. May 03, 2010 | Casio fx-300ES Calculator
