Deﬁnition 6 Given n the set of numbers which are congruent to each other modulo n is called a congruence class modulo n. The set of congruence classes for a given n are a partition of the integers. 1.2 Modular Arithmetic Theorem 7 For any integers a,b,c,d ∈ Z, if a ≡ c (mod n) and b ≡ d (mod n) then a+b ≡ (c+d) (mod n). Proof:

Our ﬁrst problem is Solve the congruence ax ≡ b mod N. Consider, for example, the congruence 1234x ≡ 1 mod 54321. It is easy to tell whether a given x satifsﬁes the congruence. For example, if x = 199 we compute 1234×199 = 245566, then compute the remainder when we divide 245566 by 54321. The result is 28282.
Around the same time interesting connections between modular forms for congruence and noncongruence subgroups began to merge. In [Sch88, Sch93] Scholl gave examples of 1 dimensional spaces of cuspform with the A(p) being eigenvalues of congruence cuspforms by showing the l-adic Scholl represen-tations associated to those cases are “modular”.
We will call two integers a and b congruent modulo a positive integer m, if a and b have the same (smallest nonnegative) remainder when dividing by m. The formal definition is as follows. Let a, b and m be integers where. .
The modular group Λ (also called the theta subgroup) is another subgroup of the modular group Γ. It can be characterized as the set of linear Möbius transformations w that satisfy. with a and d being odd and b and c being even. That is, it is the congruence subgroup that is the kernel of reduction modulo 2, otherwise known as Γ(2). References

Another way of defining the concept is to say that two numbers are congruent modulo m if m divides the difference of the two numbers (we usually assume that the modulus is greater than zero). For example, 18 and 25 both leave a remainder of 4 when divided by 7 and are therefore congruent modulo 7.

To add two congruence classes modulo n, we just select any element a from the first class and any element b from the second class, and then compute a + b as we would for normal integers. The sum of the two congruence classes is then defined to be equal to the congruence class containing the "usual" sum a + b. For example, here are the ...
Congruent? Why such a funny word that basically means "equal"? Maybe because they are only "equal" when placed on top of each other. Anyway it comes from Latin congruere, "to agree".

Once we have an inverse a of a modulo m, we can solve the congruence ax b pmod mqby multiplying both sides of the linear congruence by a. Example 3. What are the solutions of the linear congruence 3x 4 pmod 7q? Solution. We saw that 5 is an inverse of 3 modulo 7. Multiplying both sides of the congruence by 5 shows that 5 3x 5 4 pmod 7q:
Congruence classes We say two integers are in the same congruence class if they are congruent modulo m. We write [x] for the congruence class containing x, that is, the set of integers congruent to x modulo m. The set of congruence classes mod m are denoted by Z m. Z m consists of m distinct classes: , , , … , [m – 1].

If and if you consider congruences modulo 100, congruence is conserved under multiplication. So we can substitute 99 by a congruent number. And so, you can instead of multiply 99 by itself, 99 times, we can multiply -1 by itself 99 times. So, 99 to the power of 99 is congruent to -1 to the power of 99, modulo 100.
Example 1: let a = 2 and p = 7. Then ap 1 = 26 = 64. Notice that 64 = 7(9) + 1, so using the de nition for modulo we see that indeed 27 1 1 (mod 7). Example 2: Find 235(mod 7) Solution: We notice that we’re working mod 7, so by Fermat’s Little Theorem we have 26 1 (mod 7). We recall that we can take positive exponents of both

So we can write E ≡E 0 +E 1 +E 2, where for i= 0, 1, 2, E i comprises those terms in E in which the exponent is congruent to i (mod 5).

In this section, we will be discussing linear congruences of one variable and their solutions.As we have shown above, addition and multiplication modulo a prime number p form a finite field. The order of the field is p 1. However, modulo arithmetic on its own will not let us to construct a finite field with order of p m for m > 1. For example, 2 3 = 8, and we've already know (Z 8, +, *) is not a field
