\cdot for matrix multiplication and the dot product, \times for cross product and nothing (or *, if I want to write it explicitly and have no convolution in the expression) for regular multiplication.

But why

'*' is commonly used for multiplication in computer programming, so it's probably that. Also in your calculator app

** for power?

^ for power. ** is usually in a programming setting (but it‘s usually a method and not an operator there.)
