May 16, 2015 · 16 I really can't get my head around this "modulo" thing. Can someone show me a general step-by-step procedure on how I would be able to find out the 5 modulo 10, or 10 …

If you just need to calculate powers modulo some number, wolfram alpha has built-in modular exponentiation. But if you only have access to a pocket calculator (e.g. in an exam), or you're …

2 Calculate the modulo operations given below (without the usage of a calculator): $101 \times 98 \mod 17 =$ $7^5 \mod 15 =$ $12^8 \mod 7 =$ $3524 \mod 63 =$ $−3524 \mod 63 =$ Ok with …

I know how to solve mod using division i.e. $$11 \\mod 7 = 4$$ For this I did a simple division and took its remainder: i.e. $$11 = 7 \\cdot 1 + 4$$ Where $11$ was dividend, $7$ divisor, $1$ …

For example: $$7x \\equiv 1 \\pmod{31} $$ In this example, the modular inverse of $7$ with respect to $31$ is $9$. How can we find out that $9$? What are the steps that I need to do? …

I need some help with this problem: $$439^{233} \\mod 713$$ I can't calculate $439^{223}$ since it's a very big number, there must be a way to do this. Thanks.

I have attached an image showing a Modulo 2 binary division. I can roughly understand the working below which is using XOR calculation but I am not sure how the answer (in red) is …

Is it possible or not to calculate remainder through use of Casio fx-991 ES Calculator. If possible then how for example :- I have to calculate remainder of 2345763534 rem 24 and other media …

MULTIPLE PRIMES Again, if a square root exists, there are two square roots modulo each prime. So if we are using multiple primes, there can be more square roots. For example, with two …

In the context of cryptography, I need to find the private key of a message and I need to use modular arithmetic. I understand how modular arithmetic using a clock with whole numbers. …
