What does "therefore symbol" mean?
Therefore symbol ∴ is used before a logical consequence, like the conclusion of a syllogism, generally in math proof and rational argument. The "therefore sign" consists of three dots that are placed in an upright triangle. It is not commonly used in formal writing, but it is used in shorthand and mathematics.
According to "A History of Mathematical Notations," Johann Rahn used two symbols - "therefore" and "because" to signify "therefore." Other authors of the 18th century used three dots in a triangle shape to mean "therefore." Still, as with Rahn, there was not a lot of inconsistency in how the triangle was oriented. And with its current meaning, the sign appears to have originated in the 19th century. Later, in the 20th century, the three-dot notation for "therefore" became very infrequent in continental Europe, but it remains popular in Anglophone countries.
How to use therefore symbol
There are various ways in which we can use the therefore symbol. For instance, in a syllogism, we may use the sign accordingly:
- All gods are immortal.
- Zeus is a god.
- ∴ Zeus is immortal.
- x + 1 = 10
- ∴ x = 9.
However, the sign can also be used in meteorology, where "therefore, symbol" is used to signify "moderate rain" on a station model. The similar typographic symbol asterism ⁂ (created with three asterisks) indicates moderate snow.
The "therefore symbol" is also used in Masonic traditions, in which it indicates an abbreviation. For instance, "R∴W∴ John Smith" is an abbreviation for "Right Worshipful John Smith."
