How to learn Algebra:

 

      Correctly utilize basic operations like add, subtract, multiply and divide; so you     know whether you are learning the higher order algorithms correctly.

 

      Recognize patterns: Know the basic form of the functions: linear, quadratic, rational, exponential, logarithmic

 

Which model fits the data best?

 

      Learn the terminology so you can be literate in mathematics.  Example:  Teachers refer to a “bell” curve in grades.  What is linear thinking?  What does it mean to grow exponentially?  What does it mean that pH is a logarithmic scale?

 

 

      Ask yourself key questions such as:

What is the same from one section to another section? 

                                    Ex:  translating a function, order of operations, graphing a function

 

                              What is different from unit to unit? 

                                    Ex: The information needed to graph a function may differ.

 

                              What do I need to know to write quadratic functions?

 

                           When do I need to apply linear regression as opposed to using the vertex and one additional point?

 

                              What is  [b/2a, f(- b/2a) ]?   What DO ALL THE PIECES MEAN????
