to the best of my knowledge, there is three types of economic formulas people use in the real world ... ???

Algebraic Economics Education ( chances are you will not learn much of it in a public school ? ( but this could change ? ) how can you tell,

 if you had an economics class in school, how much of it did / do you understand ??? )

do you know how to immediately find a job that will take care of you and your family ???

do you know how to start a business and hire employees understanding the algebraic economics laws of physics ... ???

if you do not know how to find a job,

and you do not know how to find customers,

do you know how to survive using algebraic economics efficiency ???

Economics Efficiency ( there is many references in libraries and such on this issue ? problem usually is you need a specific economics dictionary to go with the book you are learning from ??? apparently few economics professors agree on the same definitions for the same economic words ???

example I found, Capitalism apparently has a different definition in each economics dictionary, economics professors just cannot agree on what the economics words mean ? you read one dictionary, your friend reads a different one, you think you understand one another, but maybe you don't, then you explain what you learnt to someone else in error ... ???  )

Improving the economy from the root ( you apparently get the least amount of education in the most important thing ... and apparently the hardest to find in the library or book store ??? )

the way I researched this was I asked more than 50,000 people over seven years, that is about 19 people a day or more ...

which family have you helped today to solve an algebraic economic problem in a tactful way, who has the economic skills to algebraically economically legally help your family solve a problem in a tactful way ??? 

( guaranteed, at some point(s),  your life or the life of a loved one depends on it ... !!! )
