A tour of the technical blocks. Inline math such as e^{i\pi} + 1 = 0 becomes inline code, display math becomes a real math block:

\int_{- \infty}^{\infty} e^{- x^{2}} d x = π

The hydration of a dough is the water weight divided by the flour weight:

h = \frac{m _{w a t er}}{m _{f l o u r}} \times 100

def hydration(water: float, flour: float) -> float:
    return water / flour * 100

export const hydration = (water: number, flour: number): number =>
	(water / flour) * 100;

fn hydration(water: f64, flour: f64) -> f64 {
    water / flour * 100.0
}
