1 mod 3 equals 1, since 1/3 = 0 with a remainder of 1. To find 1 mod 3 using the modulus method, we first find the highest multiple of the divisor, 3 that is equal to or less than the dividend, 1.

Feb 5, 2021 · If you ignore the meaning of $ -1 $ and consider it an arbitrary symbol, what properties does it have? By definition, it is the value such that $ (-1) + 1 = 0$. But, working …

May 16, 2015 · 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 …

Jan 27, 2015 · 0 Prove or disprove: For every integer a, if a is not congruent to 0 (mod 3), the a^2 is congruent to 1 (mod 3) SO this is for abstract algebra and I am really struggling with this. …

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. …

(The parallel is to proving there are infinitely many primes $p\equiv1\pmod4$, where Fermat's theorem on the representation of integers in the form $x^2+y^2$ is used.) There seems to be …

Apr 5, 2020 · Show that if a prime $p ≠ 3$ is such that $p≡1$ (mod 3) then p can be written as $a^2-ab+b^2$ where a and b are integers. I have no idea how to approach this question, so …
