MediaWiki menggunakan subset markah AMS-LaTeX, yaitu sebuah superset markah LaTeX yang menghasilkan superset markah TeX untuk menampilkan formula matematika. Subset ini menghasilkan gambar PNG ataupun markah HTML sederhana, tergantung preferensi pengguna dan kerumitan rumusnya. Ketika peramban web semakin canggih, subset ini akan mampu menghasilkan HTML dan MathML yang termutakhirkan (lihat blahtex untuk informasi mengenai upaya menambahkan dukungan untuk MathML.)

TeX vs HTMLSunting

Sebelum memperkenalkan markah TeX untuk menghasilkan karakter-karakter istimewa, perlu diketahui bahwa sebagaimana tabel perbandingan di bawah ini, hasil sejenis kadang dapat diperoleh melalui HTML (lihat Bantuan:Karakter istimewa).

Sintaks TeX (PNG) Hasil Sintaks HTML Hasil
<math>\alpha\,\!</math> {{math|<var>&alpha;</var>}} α
<math>\sqrt{2}</math> {{math|{{radical|2}}}} 2
<math>\sqrt{1-e^2}</math> {{math|{{radical|1 − ''e''²}}}} 1 − e²

Kode di sebelah kiri menghasilkan simbol-simbol di sebelah kanan, namun simbol-simbol tersebut dapat pula langsung diletakkan di teks wiki, kecuali ‘=’.
