Vertical bar facts for kids

For technical reasons, "|" does not redirect here.

A vertical bar is the glyph "|". It has several other names besides vertical bar, such as "pipe", "vertical slash", and "bar". In mathematics, it may be put on both sides of a real or complex number to mean its absolute value. When applied on both sides of a matrix, it means its determinant. When placed in between two numbers, it means the divisibility relation (for example. $a \mid b$ means "a divides b").

In mathematics, double vertical bars are also used to refer to various mathematical concepts. These include the parallel relation (as in $\ell_1 \parallel \ell_2$ ) and the norm of a vector (as in $\| \mathbf{v}\|$ ).
