Extract

The equation

x2 = x

expresses the condition that the symbol x be single and positive. The equation

x2 = −x

expresses the condition that the symbol x be single and negative. The principle of contradiction

x(1−x)=0

can be legitimately deduced with the help of the fundamental axioms of the science.
