Upper-case numbers look like \(0123456789\) or \(\mathrm{0123456789}\) and lower-case numbers look like \(\mathcal{0123456789}\). They’re made by using 0123456789, \mathrm{0123456789}, and \mathcal{0123456789}, respectively.
We can put a fraction \(\frac{200}{3456}\) in the middle of this sentence by using \frac{200}{3456}.
\(\mathbb{U} = \lbrace \mathbb{R}, \mathbb{C} \rbrace \) — The universal set is equal to real numbers and complex numbers.
