Cái của em chỉ toàn ra mật mã vậy ?

Hình như bạn copy+paste cái [latex] [+preamble] của anh Khuê (Nesbit) nên nó không hiện ra.

Cái mã $\LaTeX$ ghi [latex], [+preamle] của anh Khuê nếu bạn để ý kĩ thì thấy nó được tô màu ở "[" : [latex] [+preamble] (cái này mình copy trực tiếp của anh Khuê nên có màu)

Mã $\LaTeX$ sẽ không hiển thị nếu không cùng thống nhất một màu. Bạn nên gõ ra cụ thể [latex] [+preamble].
