COLOR Text and examples on MathNovatory.com, use color to highlight Qualitative aspects of items. From Numerical Structure, the source and essence of Qualitative Mathematics, each level or Stage is identified by a specific color: GREEN is the color of Addition-Subtraction (Stage 1 of Numerical Structure), where there are only integer values, which interact peacefully and compatibly with each other, between limits of positive infinity and negative infinity, with "0" as an inactive center and "1" as a preferential increment. This is where Fibonacci numbers belong. There are no times or fractions here, they will only appear in the two following structures, doubly so in Power-Root. BLUE is the color of Multiplication-Division (Stage 2 of Numerical Structure), where there are only positive values (the negative values being borrowed from the Addition-Subtraction Numerical Structure), which are incompatible with each other, between limits of positive infinity and "0", with "1" as an inactive center and "2" as a preferential increment. This is where Prime Numbers belong, and where times and fractions are born, which will be accentuated in the structure of Power-Root. RED is the color of Power-Root (Stage 3 of Numerical Structure), where there are only positive values (the negative values being borrowed from the Addition-Subtraction Numerical Structure), which are incompatible with each other, between limits of positive infinity and "1", with "2" as both center and preferential increment. A very interesting mixture of the three Stages of Numerical Structure can be found in Logarithms, which are used to multiply the values which they represent by the process of adding the logarithms, which is simpler than multiplying the original values.
