Here it is in (probably excessive) detail:
#color(red)(color(white)("")(-.75))xxcolor(blue)(5.5)#
#color(white)("XXX")=color(red)((-1)xx(75)xx(0.01))xxcolor(blue)(color(white)("")(55xx0.1))#
#color(white)("XXX")=(-1)xx75xx55xx0.001#
#{:
(color(white)("XXXx")75),(underline(color(white)(X)xxcolor(white)("x")55)),
(color(white)("XXx")375),
(underline(color(white)("Xx")375color(white)("X"))),
(color(white)("Xx")4125)
:}#
So
#color(red)(color(white)("")(-.75))xxcolor(blue)(5.5)=(-1)xx4125xx(0.001)#
#color(white)("XXXXXXXX")=-4.125#
