Wolfram alpha congruence modulo

Mathematica Stack Exchange is a question and answer site for users of Wolfram Mathematica. It only takes a minute to sign up. I am attempting to create a list of the invertible congruence classes $\bmod 120$. The code I have is Table[If[{ModularInverse[i, 120 ]} = {}, 120, ModularInverse[i, 120]], {i, 0, 119}] If the modular inverse does not exist, it should return $120$. If it does exist, it should return the integer …

Let one solution to the original equation be .Then the solutions are , , ,, .If , then there is only one solution .. The solution of a linear congruence can be found in the Wolfram Language using Reduce[a*x == b, x, Modulus -> m].. Solution to a linear congruence equation is equivalent to finding the value of a fractional congruence, for which a greedy-type … If I need to find the solutions of: x^2 ≡ 8 (mod 23) and I use the above formulas, I get the solution: x = +- 13, but Wolfram Alpha says that +-10 also works (and it does). So why is that? Why do these formulas only give you 1/2 of the answer and why can't I find a way to find the whole answer (excluding the way where you draw the table with x^2 mod p for x from 0 to p and)? I realize that I'm probably doing … Wolfram Science.

For example, the modulo of powers of 2 can alternatively be expressed as a bitwise AND operation (assuming x is a positive integer, or using a non-truncating definition): Wolfram Science.

Mar 10, 2021 · Modular arithmetic is the arithmetic of congruences, sometimes known informally as "clock arithmetic." In modular arithmetic, numbers "wrap around" upon reaching a given fixed quantity, which is known as the modulus (which would be 12 in the case of hours on a clock, or 60 in the case of minutes or seconds on a clock).

$$3y\equiv1\mod527$$ The question says to Express our answer in the original modulus of 777 but I end up with 130mod(259) which is right according to wolfram alpha so how do I convert it to mod 777? I notice that 777=259(3) but I don't think I'm allowed to just multiply the modulus by 3 to make it work. Any ideas? Since I'm not going to be tested on this, I can just ask Wolfram Alpha: ChineseRemainder[{2, 5, 1}, {3, 7, 8}]. Besides, the steps to solving simultaneous congruences are covered in other Math.SE questions and answers.

For example: If I need to find the solutions of: x^2 ≡ 8 (mod 23) and I use the above formulas, I get the solution: x = +- 13, but Wolfram Alpha says that +-10 also Modulo operations might be implemented such that a division with a remainder is calculated each time.

The CRT says there is at least one that solves them all Given a possible congruence relation a â ¡ b (mod n), this determines if the relation holds true (b is congruent to c modulo n). Correlation and Regression Calculator. To embed this widget in a post, install the Wolfram|Alpha Widget Shortcode Plugin and copy and paste the shortcode above into the HTML source. In general, you can skip parentheses, but be very â ¦ (Symmetry) if a â ¼ b then b â ¼ a, 3. … Mathematica Stack Exchange is a question and answer site for users of Wolfram Mathematica.

Mod[m, n] gives the remainder on division of m by n. Mod[m, n, d] uses an offset d. Get the free "Inverse of an integer x modulo n" widget for your website, blog, Wordpress, Blogger, or iGoogle. Find more Mathematics widgets in Wolfram|Alpha. Wolfram Science.
