几乎在我们意识到之前，我们已经离开了地面。
우리가 그것을 알기도 전에 우리는 땅을 떠났습니다.
私たちがそれを知るほぼ前に、私たちは地面を離れていました。
Block math works with two dollar signs $$...$$
$$f(x) = \int_{-\infty}^\infty
f\hat(\xi),e^{2 \pi i \xi x}
\,d\xi$$
Inline math also works with single dollar signs $...$. For example, Euler's identity but inline: $e^{i\pi} = -1$
Aligned equations work quite well:
$$
\begin{aligned}
a &= b + c \ &= e + f \
\end{aligned}
$$
And matrices
$$
\begin{bmatrix}
1 & 2 & 3 \
a & b & c
\end{bmatrix}
$$
