May 8, 2025 - You can't just add 8 to 11, as there is no such time as 19 am. To find the correct answer, perform a modulo operation (mod 12) — add these two numbers and keep subtracting 12 until you get a number lower than 12. In this case, 7.

The modulo operation finds the remainder of a divided by b. To do this by hand just divide two numbers and note the remainder.
How much is 17 mod 3?
17 mod 3 equals 2 since dividing 17 by 3 gives a quotient of 5 and a remainder of 2. The remainder is the result of the modulus operation. In simpler terms, 17 mod 3 = 2.

1 week ago - A familiar setting exhibiting modular arithmetic is the hour hand on a 12-hour clock. If the hour hand points to 7 now, then 8 hours later it will point to 3. Ordinary addition would result in 7 + 8 = 15, but 15 reads as 3 on the clock face.

For instance, if we add the sum of 2, 4, 3 and 7, the sum is congruent to 6 (mod 10). That’s 16 ≡ (mod 10). This means 16 divided by 10 leaves a remainder of 6. Likewise, 16 – 10 = 6. Another example, 13 ≡ 1 (mod 12). This means 13 divided by 12 leaves a remainder of 1.

Let’s say you have a machine that takes any input number, multiplies it by $3$, and then reduces the result modulo $7$. If you enter $4$, the machine does: $3 \cdot 4 = 12 \mod 7 = 5$ You get $5$ as the output. But what if someone else sees $5$ and wants to figure out what number was entered?

December 7, 2024 - Modulo can be understood in terms of repeated subtraction. It subtracts the divisor from the dividend until the remainder is less than the divisor. For example: $$23 \bmod 7$$: Subtract 7 repeatedly from 23: $$23 - 7 - 7 - 7 = 2$$. Thus, $$23 \bmod 7 = 2$$.

You can see the pattern 0, 1, 0,1 … for mod 2. Can you guess the pattern for mod 3? It is 0,1,2,0,1,2 and so on. So it can be said that the pattern consists of Divisor-1 digits. If the divisor is 4 then the pattern is 0,1,2,3,0,1,2,3 … . Hopefully, you understood. ... We know that after twelve, the clock strikes one, and the circle starts again. If we replace 12 with 0, a clock will be a perfect example of mod 11.

r/learnmath on Reddit: How come -7 mod 3 is 2?
June 19, 2024 -
I come from a computer science background and my mind is exploding rn from this.
In programming languages the % represents the modulo operation.
In most programming languages like C, Rust, Java, JavaScript -7 % 3 results in -1, this makes sense to me logically since if I have "negative 7 dollars" divided it across three people, each will get "-2 negative dollars" and "-1 negative dollar" will remain.
So how come in any calculators, and the few mathematics-friendly programming languages like Python and Haskell, -7 % 3 results in 2? Like logically speaking how could dividing a negative number result in a positive number, and where did the 2 even came from, from a logical standpoint?

Here’s a way to think about it that could help. In “mod 3”, each integer has to be in (exactly) one of three equivalency classes: 0, 1, or 2. You can list elements in each, keeping in mind that consecutive elements in each class are distanced from each other by the modulus (in this case, 3). The “0 class” contains { …, -9, -6, -3, 0, 3, 6, 9, … }. All elements in this set are equivalent to 0 mod 3. Each element can be achieved by starting at 0 and going up or down, counting by 3. The “1 class” contains { …, -8, -5, -2, 1, 4, 7, 10, … }. All elements in this set are equivalent to 1 mod 3. Each element can be achieved by starting at 1 and going up or down, counting by 3. The “2 class” contains { …, -7, -4, -1, 2, 5, 8, 11, … }. All elements in this set are equivalent to 2 mod 3. Each element can be achieved by starting at 2 and going up or down, counting by 3.

How come -7 mod 3 is 2? For a, b ∈ ℤ, and n ∈ ℤ \ {0}, a ≡ b (mod n)means∃ q, r ∈ ℤ. a = qb + r. (Think ofqas the quotient, andr` as the remainder. They are not unique, so calling them "the quotient" and *"the remainder" is not strictly correct, but it's ok as an intuition. More on this below.) So, for what you're asking: -7 ≡ 2 (mod 3) because -7 = (-3)·3 + 2. But also: -7 ≡ -1 (mod 3) because -7 = (-1)·3 + 2. So, both -1 and 2 make perfect sense when it comes to picking out a result when you want to pick a representative for the congruence relation. Like logically speaking how could dividing a negative number result in a positive number, and where did the 2 even came from, from a logical standpoint? For a ∈ ℤ and b ∈ ℕ \ {0}, there exist unique q, r ∈ ℤ such that a = qb + r and 0 ≤ r < b. We say that q is the quotient and r is the remainder of division of a by b. (Note that we now do have uniqueness.) It is this definition of the remainder, which insists that the remainder has to be between 0 and the divisor, that's being used when setting -7 % 3 = 2 in programming languages that want their operands to be better aligned with commonly used mathematical definitions.
