I am currently a Mathematics teacher in Baptist Lui Ming Choi Secondary School.
I like Logic, Real analysis and Number theory.
Besides Mathematics, I love movies and classical music. I have deep interest in Japanese culture.

LaTeX is a common typesetting interface for typing mathematical documents, such as lecture notes and journals. Do you think I use LaTeX to type the notes available on this site? No! I simply use Microsoft Word and MathType in Windows 10. Let me show you how!
Step 1: Download and install MathType 7 here.
Step 2: Download "Latin Modern Roman Font Family" here, and then install the fonts you need. (For me, most of the time I only use "Roman 10", "Roman Caps 10", "Sans 10" and "Mono 10".)
Step 3: In Microsoft word, choose the font you want and you can start to type.
Step 4: To input a math equation, complete the following procedures:
Navigate to "MathType" toolbar in Microsoft Word, and then click "Insert Inline Equation" (Ctrl+Alt+Q).
Navigate to "Style > Define" in MathType. Change the Primary font to "LM Roman 10" and the Greek and math to "Euclid Symbol and Euclid Extra". Then click "OK".
If you want to turn on TeX language entry, navigate to "Preferences > Workspace Preferences". Check the box for "Allow TeX language entry for the keyboard". Then click "OK".
Now you can type your math equation! Close MathType when you finish it, and the equation will appear in Microsoft Word.
Step 5: To save the document as PDF, do NOT use "save as". (The fonts will appear to be blurry in the PDF if you do so.) Instead, use "Print" and select "Microsoft Print to PDF". There you go!
(Of course, one can easily check that the PDF is not typed using LaTeX by checking the fonts in the PDF − they are formatted in "TrueType" instead of "Type 1". However, this is a good substitute for someone like me who doesn't know coding.)
