Using the canonical commutation rule

to commute

to the left of each term.

— exponent of the operators

and

scale results — determine whether the contents should shrink to fit in the display area

Applying the canonical commutation rule

is a fundamental operation in quantum mechanics. This shows all steps in getting powers of p to the left.
