The expression 2 mod 3 refers to the modulus operation, which finds the remainder when one number is divided by another. In this case, we’re looking for the remainder when 2 is divided by 3.
When you divide 2 by 3, it fits 0 times because 2 is less than 3. The remainder is therefore simply the original number, which is 2. Thus, we can conclude that:
- 2 mod 3 = 2
This operation is often used in various fields such as computer science and mathematics to work with cycles or to restrict values to a certain range.
