This is a paragraph. Here's an inline math example: \( a^2 + b^2 = c^2 \).
And a display math example:
\[ \int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi} \]what the sigma!
\[ \int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi} \] \[ \int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi} \] \[ \int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi} \]
