I am unable to find the modulo of the numbers

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.

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.

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.

Re: appcrash
Vista
Go to Start > Type in .....cmd........right-click on cmd and select "Run as administrator".
After the cursor paste in : SFC /SCANNOW and press your 'Enter' key.

This procedure will scan Vista's protected system files
and attempt to repair or replace missing or corrupt files.

XP
Use the Administrator account
Go to Start > Run - Type in ....cmd.... > OK.
After the cursor paste in : SFC /SCANNOW and press your 'Enter' key.

This procedure will scan XP's protected system files
and attempt to repair or replace missing or corrupt files.

If the result shows that the corrupt files are unable to be repaired, go for a 'banket' repair using Yahoo Messenger Help

Pueden ser una de dos cosas.
1. Fuente de poder esta defectuosa y no produce el suficiente amperaje para todos los componentes de tu micro.
2. Algun modulo de memoria esta fallando.

Comienza removiendo los modulos de memoria, y conecta solo una.
Enciende la micro a ver si enciende.
Si no, sacala, y coloca otro modulo, y enciendela.

Si no lo consigues, prueba con otra fuente de poder.
Una de las dos es tu respuesta.

I did a google search using the words "congruent modulo Computer speakers" perhaps you might want to do this too.
