I don't think that Schremmer wants to change the colour of this line,  
he rather wants to emphasise on this particle and build a relation  
between a negative exponent (starting with a line like -) and  
dividing 1 exponent times by the number, i.e., 1 over (another line)  
number \times number \times number ... And similarly for positive

The mathematician who pursues his studies without clear views of this  
matter, must often have the uncomfortable feeling that his paper and  
pencil surpass him in intelligence.
