Yes, you can potentially get a copyright for a new method of writing multiplication tables.

If your method is original, creative, and fixed in a tangible form (like a book, document, or software), it could qualify for copyright protection. Copyright protects the expression of an idea, not the idea itself.

However, there are some important points to consider:

Originality: Your method must be substantially different from existing methods. A minor variation or improvement might not be considered original enough.

Fixation: You need to have expressed your method in a tangible form. For example, writing it down, creating a diagram, or coding it into a software program.

Public Domain: If the method is already in the public domain (known and freely available), it cannot be copyrighted.

If you believe your method meets these criteria, it's advisable to consult with a copyright attorney for a more comprehensive evaluation and guidance on the copyright registration process.

Copyright generally protects original works of authorship, such as literature, music, art, and software. However, it does not typically extend to methods, systems, or procedures. If you've discovered a new method for writing multiplication tables, copyright wouldn't apply because it's a process or technique, not a creative expression like a book or article.

That said, your method could be protected through other forms of intellectual property. For example, if your method is innovative and not obvious, you might consider applying for a **patent**. Patents protect inventions, including new methods of doing something, but they require a more rigorous application process, and the idea must be truly novel and non-obvious.

You can also consider **trademarking** the name of your method if you plan to market it under a specific brand. This would prevent others from using the same name for a similar method.

In short, while copyright may not apply to your method of writing multiplication tables, exploring patent or trademark protection might be a better route if you want exclusive rights to your idea. You can consult an intellectual property lawyer to determine the best way to protect your innovation.
