A rule can be a rule or precept, an established way of performing something, a method for performing mathematical operations, a woman’s menstruation, or an instrument for measuring or drawing straight lines, among other things. The word, as such, comes from Latin regulate.
Rule, norm and law
In law, a distinction is made between the concepts of rule, norm and law. The rule, for example, is any precept of conduct that is established based on what should be. It applies to specific situations.
The norm, for its part, refers to a legal provision or precept that imposes duties and confers rights, and that is established in accordance with use, contract or practice. It is, in hierarchical terms, above the rule and below the law.
The law, on the other hand, is the mandatory legal norm. It has a general nature and is dictated by a legitimately constituted power that has the power to regulate the conduct of people. It is in a position superior to the norms, but inferior to the constitution.

spelling rule
In linguistics, we talk about orthographic rules when we refer to the set of rules that establishes how each of the graphic signs that make up the writing system of a language should be used. Spelling rules are established by tradition or convention, and allow us to determine the correct spelling of words.
Spelling rules are, for example, those that determine the use of accent, the union or separation of words, clarify what is the correct writing in words with similar sounds written with letters such as b either v, g either j, yes either cetc.

rule in mathematics
In mathematics, we call a method for doing mathematical operations a rule. In this sense, the rule establishes the sequence that must be followed in operations to reach the correct result. An example of a mathematical rule is, for example: the rule of three, with which we can find the solution to proportionality problems between three or more known values and an unknown.
Period (menstruation)
A woman’s menstruation is known as a period. It is the product of a natural physiological process in women of reproductive age. In this process, women expel an unfertilized egg through the vagina, which comes out in the form of blood flow. The bleeding can last several days, and repeats about every 28 days.
Graduated ruler (instrument)
The graduated ruler is an instrument used to measure distances or to draw. It is usually flat and rigid. It allows you to determine the distance between two points or draw straight lines. It usually has a scale graduated in different units of length, which can be centimeters, decimeters or millimeters. It is widely used in technical drawing.
