    The equations are mostly correct, but variable names are swapped. The text has the wrong descriptions for some variables. Example, in the formula y = a + bx, the text describes 'a' as the slope of the regression line, and 'b' as the intercept. Then, it calculates b as the intercept and a as the slope, so the equation y= b + ax is the correct equation.

    So simple, easy to understand even for non statistics students. I hope you can add more statistics topics such as non parametrics, multivariate, etc.
