How to type Ast

Write \ast inside math mode, that is between $…$ for inline math or in a \[ … \] or equation block for display math. It is part of core LaTeX math, so no extra package is required.

As a binary operator, \ast gets a medium space on each side; at the start of a formula LaTeX reads it as a sign and drops the space. With unicode-math under XeLaTeX or LuaLaTeX, typing ∗ in a formula gives the same symbol.
