1. Associated with any particle moving in a conservative field of force is a wave function which determines everything that can be known about the system.

2. With every physical observable q there is associated an operator Q, which when operating upon the wavefunction associated with a definite value of that observable will yield that value times the wavefunction. 

3. Any operator Q associated with a physically measurable property q will be Hermitian. 

4. The set of eigenfunctions of operator Q will form a complete set of linearly independent functions. 

5. For a system described by a given wavefunction, the expectation value of any property q can be found by performing the expectation value integral with respect to that wavefunction. 

6. The time evolution of the wavefunction is given by the time dependent Schrodinger equation.

This should help one ease into quantum and wave mechanics.

It's interesting to see the development of the mathematics in parallel with the physics.
