# Latex not subset symbol

The not subset symbol in LaTeX is denoted by the command \not\subset. It is used to indicate that one set is not a subset of another set.

## The Not Subset Symbol in LaTeX

The not subset symbol in LaTeX is denoted by the command \not\subset. It is used to indicate that one set is not a subset of another set.

The command \not\subset can be used in both inline math mode and display math mode. In inline math mode, the not subset symbol is smaller and appears to the right of the expression, while in display math mode, the not subset symbol is larger and appears below the expression.

## Inline Math Mode

In inline math mode, the not subset symbol is smaller and appears to the right of the expression. For example, the expression $A \not\subset B$ is typeset as follows:


$A \not\subset B$


$A \not\subset B$

## Display Math Mode

In display math mode, the not subset symbol is larger and appears below the expression. For example, the expression

$$A \not\subset B$$

is typeset as follows:


$$A \not\subset B$$


$$A \not\subset B$$

## Exemples

The not subset symbol can be used to indicate that one set is not a subset of another set. For example, if $A$ is the set of all positive integers and $B$ is the set of all even integers, we can write $A \not\subset B$ to indicate that not all positive integers are even.

## Conclusion

The not subset symbol in LaTeX is a commonly used mathematical symbol that is used to indicate that one set is not a subset of another set. It can be used in both inline math mode and display math mode by using the command \not\subset.
