Cosa c'è di sbagliato in questo allineamento?
Contesto:
Innanzitutto, mi scuso per il lungo post.
Quindi sto usando l'ambiente di allineamento per la prima volta nel mio documento articolo LaTex, ma non con molto successo. Ecco il mio preambolo per il mio articolo:

Domanda
In questo articolo, volevo allineare alcune equazioni, quindi ho utilizzato il seguente codice basato su alcune guide online:
We can now use the Pythagorean Theorem to find PE in two different equations which utilise $x$ and hence solve for $x$:
\emph{From $\triangle$PEB:}
\begin{align*}
PE &= $\sqrt{BP^2 - x^2}$ \\
&= $\sqrt{10^2 - x^2}$ \\
&= $\sqrt{100 - x^2}$
\end{align*}
Tuttavia, ottengo questo come risultato:

E anche il registro degli errori sembra correggersi da solo correggendo me (cioè corregge qualcosa, quindi cerca di correggere quella correzione che pensa non sia corretta ... sai una cosa? Guarda il registro :)

Quindi fondamentalmente tutto il registro degli errori fatto è stato confondermi e non sono abbastanza sicuro di cosa fare. Aiuto apprezzato per risolvere questo problema!
Grazie!

Quindi, come sottolineato nei commenti, questa è una soluzione relativamente semplice, in altre parole una risposta relativamente breve per un post lungo :):

\begin{align*} PE &= \sqrt{BP^2 - x^2} \\ &= \sqrt{10^2 - x^2} \\ &= \sqrt{100 - x^2} \end{align*}
