$a^2 + b^2 + c^2 \geqslant ab + ac + bc$

Codul formulei matematice (încadrate de simbolurile dolar):
a^2 + b^2 + c^2 \geqslant ab + ac + bc




Formulele LaTeX trebuiesc încadrate între simbolul dolar 
(...la stânga și la dreapta formulei)

Recurența combinărilor (clasa a 10-a)

$\displaystyle \binom{n}{k} = \binom{n-1}{k} + \binom{n-1}{k-1}$

Codul "formulei" matematice (formulei/expresiei LaTeX)

Code:
$\displaystyle \binom{n}{k} = \binom{n-1}{k} + \binom{n-1}{k-1}$



$\LaTeX$

$\displaystyle \frac{2^n}{2} = 2^{n-1}$ = \displaystyle \frac{2^n}{2} = 2^{n-1}

\displaystyle în cazul unor radicali:

$\sqrt \frac{n^2+1}{2^n-7}$ ...respectiv  $\displaystyle \sqrt \frac{n^2+1}{2^n-7}$

adică:

\sqrt \frac{n^2+1}{2^n-7} ...respectiv  \displaystyle \sqrt \frac{n^2+1}{2^n-7}

media armonică $\leqslant$ media geometrică $\leqslant$ media aritmetică $\leqslant$ media pătratică 

$\displaystyle \dfrac{n}{\dfrac{1}{a_1} + \dfrac{1}{a_2} + ... + \dfrac{1}{a_n}} \leqslant \sqrt[n]{a_1 a_2 ... a_n} \leqslant \dfrac{a_1 + a_2 + ... + a_n}{n} \leqslant \sqrt{\dfrac{a_1^2 + a_2^2 + ... + a_n^2}{n}}$

Modul «mare» (și în general folosirea/prefixarea cu \left... și \right...)

$\left|\frac{42}{1+x^4}\right|$

\left|\frac{42}{1+x^4}\right|

Iar cu \displaystyle la început:

$\displaystyle \left|\frac{42}{1+x^4}\right|$

Alte variante reies din folosirea big, Big, bigg și Bigg.
