Math

Basics

To render any math equation, the math equation must be between <math></math> i.e., <math>f(x)=x^2</math> gives Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle f(x)=x^2} .

Common math commands

Superscript & Subscript

Superscript: <math>x^{5+y}</math> gives Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle x^{5+y}}

Together: <math>x_{5+t}^{5+y}</math> gives Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle x_{5+t}^{5+y}}

Fractions & Radicals

Fractions: <math>\frac{1}{x}</math> gives Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle \frac{1}{x}}
Square root: <math>\sqrt{x+1}</math> gives ${\sqrt {x+1}}$
General Radical: <math>$\sqrt[3]{64}=4</math> gives ${\sqrt[{3}]{64}}=4$
