In math, the vertical bar symbol (|) has several uses, depending on the context:
-
In set notation, it’s typically seen in expressions like this:
This means “the set of all such that is a real number and is greater than ”.
-
As an absolute value symbol, it might be seen in expressions like this:
This is read as “the absolute value of -3”, which is 3, because absolute value represents the magnitude of a number, regardless of its sign.
The colon symbol is used in math to denote a condition for a statement. The symbol can be read as "such that" in a math expression.
The notation for taking the absolute value is two vertical lines on either side of the expression being evaluated.
