# MathTex

Qualified name: `manim.mobject.text.tex\_mobject.MathTex`

### *class* MathTex(\*tex_strings, arg_separator=' ', substrings_to_isolate=None, tex_to_color_map=None, tex_environment='align\*', \*\*kwargs)

Bases: [`SingleStringMathTex`](manim.mobject.text.tex_mobject.SingleStringMathTex.md#manim.mobject.text.tex_mobject.SingleStringMathTex)

A string compiled with LaTeX in math mode.

### Examples

### Tests

Check that creating a [`MathTex`](#manim.mobject.text.tex_mobject.MathTex) works:

```default
>>> MathTex('a^2 + b^2 = c^2') 
MathTex('a^2 + b^2 = c^2')
```

Check that double brace group splitting works correctly:

```default
>>> t1 = MathTex('{{ a }} + {{ b }} = {{ c }}') 
>>> len(t1.submobjects) 
5
>>> t2 = MathTex(r"\frac{1}{a+b\sqrt{2}}") 
>>> len(t2.submobjects) 
1
```
