Modulus of function - Casio FX9750GII Graphic Calculator

Calculating the modulus of large numbers can be tricky, especially when using a calculator that doesn't directly support the modulus operator. Let's break down how you can find 11^7 mod 6791496 step by step:

First, divide the exponent (7) into smaller pieces. For example, you can split it into 3 + 2 + 2 (since 7 = 3 + 2 + 2).
Calculate the following values:
(11^3 \mod 6791496)
(11^2 \mod 6791496)
Using your calculator, you can compute these values individually:

(11^3 \mod 6791496) is approximately 112.
(11^2 \mod 6791496) is approximately 118.
Multiply these three values together: (112 \times 118 \times 118).
Taking the modulus of the result with 6791496, we get the final answer:

[ (112 \times 118 \times 118) \mod 6791496 = 1559488 ]

Therefore, 11^7 mod 6791496 is equal to 1559488.

Remember that this method works well for calculators that don't have a direct modulus operator. If you have access to a more advanced calculator or software, you can use built-in modular exponentiation functions for faster results.

Additionally, some Casio calculators allow you to use the "ab/c" button as a makeshift modulus operator. You might want to check your specific calculator's user guide for any additional features related to modulus calculation.

The calculator does not have a utility to perform Modulo calculations.

This is a financial/business calculator not a scientific one.

Like many other Casio calculators, the fx-83GT Plus doesn't provide the modulus function. You have to do it the hard way.
To calculate 19 MOD 10 (which is 9, not 10 as you state in your question), first divide 19 by 10 and note the integer portion of the result (in this case, 1). Then subtract from 19 the product of 10 and the result of the first step. The result of the subtraction is the modulus. 19 - (1*10) = 9.

Divide 121 by 187. Subtract the integer portion (in this case, 0). Multiply by 187.

The lack of a modulus function is a serious flaw in that generation of Casio calculators.

To enter the MOD( function on the command line:

1. Press Menu
2. Press 1 or select icon Run>Mat.
3. In Run>Mat screen, press the OPTN key.
4. Press F6> to pan through the other options.
5. Select F4:Num and press F6:> to get other tabs
6. Press F4:MOD

Example: MOD(278,9)=8

An alternative way is to use the Catalog.

1. Press [Shift][4] (catalog)
2. Press [ALPHA][7] to jump to letter M
3. Scroll down from there to reach the MOD( command.

Actually, the answer is 79.

The fx-115ES does not have a key for the modulus operation. Nor does it have an integer-part or fractional-part operation. However, it is possible to calculate the remainder using integer arithmetic.

Press MODE 4 to shift into integer mode. Then type in 3 5 2 - 9 1 * ( 3 5 2 / 9 1 ) = and see the answer 79. It's a pain as both numbers have to be entered twice, but it does get the job done.

To get back to working with real numbers again, press MODE 1 ( or MODE 2 for complex).

This calculator does not support the modulus operation directly, you have to simulate by a divide followed by a subtraction and a multiplication. Suppose you want to calculate 256 mod 17:

1. Key in 256 [÷] 17 [=] and get the result 15,0588...
2. Note the 15 in front of the decimal separator and key in [−] 15 [=]
3. Get the modulus: [×] 17 [=], result should be 1.

using switch case statement is possible.
