In logical argument and mathematical proof, the therefore sign, ∴, is generally used before a logical consequence, such as the conclusion of a syllogism. The symbol consists of three dots placed in an upright triangle and is read therefore. While it is not generally used in formal writing, it is used in mathematics and shorthand.
Used in a syllogism:
All gods are immortal.
Zeus is a god.
∴ Zeus is immortal.
and in mathematics:
x + 1 = 10
∴ x = 9
In meteorology, the 'therefore' sign is used to indicate 'moderate rain' on a station model; the similar typographic symbol asterism (⁂, three asterisks) indicates moderate snow.
In Freemasonry traditions, the symbol is used to indicate a Masonic abbreviation (rather than the period mark used conventionally with some abbreviations). For example, "R∴W∴ John Smith" is an abbreviation for "Right Worshipful John Smith" (the term Right Worshipful is an honorific and indicates that Brother Smith is a Grand Lodge officer).
The symbol has a Unicode code point at U+2234 ∴ THEREFORE (∴, ∴, ∴).

x+8= 28,
∴ x=20.
∴ x=20.
