equation

Equations express mathematical notation in LaTeX syntax as block or inline elements.

Block equations

Block equations start with $$ and continue as an equation block.

$$ c = \pm\sqrt{a^2 + b^2}

Rendered

Inline equations are enclosed by $$...$$ within paragraph text.

Example: The identity $$a^2+b^2=c^2$$ is well known.

Equation rendering is performed by a math typesetting library, so use valid LaTeX syntax for reliable output.
