Let’s write a few Latex expressions to check that they are displayed correctly.

## Inline expressions

Let \(F_0 = 0\) and \(F_1 = 1\). The Fibonacci sequence is defined by \(F_n = F_{n-1} + F_{n-2}\) for \(n > 1\).

## Display expressions

Let’s write again the Fibonacci sequence, but this time as a display expression: \[ F_n = F_{n-1} + F_{n-2}, \forall n > 1\]

Let’s also try to display a very simple system of linear equations: \[ \left\{ \begin{aligned} 3 x_0 + x_1 &= 5 \\ 5 x_0 + 7 x_1 &= 11 \end{aligned} \right. \]
