Multiple regression coefficients

I am attempting to gain a better understanding of the multiple
regression coefficients. I have understood that the order in which the
variables are presented in the model is critical. This is because each
successive beta weight represent the covariance (correlation) with the
dependent variable while partialing out the contribution of preceding
variables in the regression equation.

I am attempting get the correct form of the equation. Many text books
present the matrix notation for the regression equation however the
matrix notation has been unhelpful in helping me to understand how
regression equation partials out the contribution of preceding
variables in the regression equation. In short, would you have
knowledge of where I could obtain the deviation score formula for
multiple regression (i.e., more than two predictors), standardized and
unstandardized?
