Therefore Symbol

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."

How to type "therefore symbol" in Apple

If you want to type the symbol in Apple, you should use the shortcut Ctrl+Command+Space to open the Character Viewer. On the left side, select Math Symbols, then click down once in the scroll bar area, and you will immediately see the ∴ symbol. Next, double-click the sign to insert it into your document, then close Character Viewer.

If you want, you can add "therefore symbol" to Word's AutoCorrect. Now that the sign is in your document copy it. Then, un Word's Preferences, go to AutoCorrect. Choose what code you want your Word to replace with ∴ sign whenever you type it. The 2-letter code "tf" seems reasonable, but select something that is easy and will not come up in the course of regular typing — ever. Once doing so, put that code into the "Replace: box" and then paste ∴ the symbol into the "With box." Next, hit "Add" and close Preferences.

Finally, whenever you type "tf" as a "word," the Word document will replace it with ∴ a symbol; Meaning that another alphanumeric character does not immediately precede it. Also, it is not immediately followed by another alphanumeric character.

How to use and type Therefore symbol code?

  • If your keyboard contains separate NumPad, you should be sure that it is enabled. If it is not, press the Num Lock key to activate it then press hold down the Alt key on the left side. Type the number that represents that character or the symbol you want to insert and then release the insert key.
  • For example, for the greek letter omega Ω press and hold Alt and the type 0234 and then release.
  • There is another method that works only for word documents. In this method, you should type the characters first then press Alt and X. For example ( 0234 + Alt + X for greek letter omega ).
  • If you have a keyboard that doesn't have NumPad here is what will work for you. Find the Function key ( FN ) then presses and hold the function key while holding press and release Num LK key; then release FN key. This method will activate the numeric keypad in your laptop.
  • Then do the same steps as in the previous example.
  • Notice that in IBM code you don't use 0 (Alt + 255 ) before the code which is different from the windows generator that requires to add 0 (Alt + 0255 ) before the code.

Something doesn't work?

  • The Num lock should always be enabled. If it is disabled when you are attempting an alt code, it may cause errors or unexpected results in some applications. For example, Alt+4 could be interpreted as Alt +, ← which causes the browser to go back if the Num lock is disabled.
  • If your laptop keyboard doesn't have a separate NumPad, you should hold FN button with Alt button while typing the code.
  • This method does not work for Linux system, but it is possible to use Unicode.
