What are the six basic primitives in Turing Complete

I am listening the edX lesson, and the professor stresses that every machine able to perform those six basic primitives can be called Turing Complete. But what are the six basic primitives?

The six basic operations/primitives that gives a language Turing completeness are:

• Right: Move the Machine’s head to the right of the current square
• Left: Move the Machine’s head to the left of the current square
• Print: Print a symbol on the current square
• Scan: Identify any symbols on the current square
• Erase: Erase any symbols presented on the current square
• Nothing/halt: Do nothing
