$x^{2}$

$yx^{5}z$
(1)$x^{2} = 5$

And then

(2)$y^{x} = z$
By (1), we have that …, whilst by (2) we have that …

a) Hello

b) Hello

$\lfloor \frac{n}{2} \rfloor$

$\sum_{i=3, 5, 7, 11} \lfloor \frac{22}{i} \rfloor - \sum_{i=15, 21} \lceil \frac{22}{i} \rceil$.

We have that the number of primes in $R$ is less than or equal to

$\sum_{i=3, 5, 7, 11} \lfloor \frac{22}{i} \rfloor - \sum_{i=15, 21} \lceil \frac{22}{i} \rceil,$

which is equal to
