How to write equations in html? [closed]

I want to write some complex mathematical equation in my web page. Is there any plugin or anything for this?

How do I type math symbols in HTML?

Many mathematical, technical, and currency symbols, are not present on a normal keyboard. To add such symbols to an HTML page, you can use the entity name or the entity number (a decimal or a hexadecimal reference) for the symbol.

Which tag is used to write mathematical formulas HTML?

The MathML element is used to include mathematical expressions and equations in an HTML page.

Try mathjax http://www.mathjax.org/ . I personally find it very good.

For complex equations, MathJax is the current practical solution. MathML is a more structural approach in principle, but browser support is rather limited and often of questionable quality.

However, complexity is relative. To some people, E = mc² or ∂/∂t + v ⋅ ∇ might be complex, and such constructs can be written fairly well using just HTML with some help from CSS; see my page Math in HTML (and CSS).
