The study raised the question of knowledge generation, in attempt to answer this question an economic model was introduced, namely, aggregate demand and aggregate supply. The final target equations can be solved by general rule (deterministic) of solving quadratic equations. The study use analytical geometry and matrix algebra tools to solve the model beside testing their stability characteristics. If we reach unique value to the price equilibrium level then income equilibrium level the maximum potency of the economy can determined. Accordingly the rest of model values would be solved spontaneously. The essential derived result is the relationship between the dependent variable and independent variable can be redefined into accommodated and...
