What is a "bullet operator"?
The bullet operator is a small dot symbol (∙) used mainly in math and science. It looks like a tiny, centered point, similar to a bullet point you see in lists, but it has a different job. Instead of organizing information, the bullet operator shows a kind of multiplication or other special operations between numbers or objects. You might see it in formulas, equations, or programming languages to make things clearer. It's not used in everyday writing but is important when working with math or technical subjects.
Examples
In the formula, the bullet operator ∙ indicates multiplication between the two vectors.
To distinguish it from a decimal point, some mathematicians prefer using the bullet operator in their calculations.
