I've moved your question to the InDesign forum.
InDesign isn't an easy program to learn by yourself, but you should start by looking at the tutorials available here:
It would be a really good (and inexpensive) idea to get a copy of Sandee Cohen's Visual QuickStart Guide. She takes you through it step by step:
Yes – Steve's right you need some help. Lynda.com have a simple introductory online course that will get you started – and I believe you can get free access to the site for a week or so: Watch the Online Video Course Getting Started with InDesign
If you have problems with specific issues, then post them on this forum for lots of speedy and friendly help.
Thank you very much for the reply. Is InDesign good to write maths textbooks with all its diagrams, graphs, symbols, shapes, notation, etc.?
No. Not for a beginner, and not for "writing".
There is a difference between "writing" a text, and designing the layout of text. InDesign is bad in the former, good -- in the hands of an expert -- in the latter. (In fact, concerning the "writing" part: InDesign is one of the worst possible choices to write in. Use Word, TextEdit, or anything else.)
Thank you Derek
