13.8x17.5-13.7x176
=13.7x17.5+0.1x17.5-13.7x176
=13.7x(17.5-176)+1.75
=13.7x(-158.5)+1.75
=(14-0.3)x(-158.5)+1.75
=-14x158.5+0.3x158.5+1.75
=-2219+47.55+1.75
=-2219+49.3
=-2169.7
=13.7x17.5+0.1x17.5-13.7x176
=13.7x(17.5-176)+1.75
=13.7x(-158.5)+1.75
=(14-0.3)x(-158.5)+1.75
=-14x158.5+0.3x158.5+1.75
=-2219+47.55+1.75
=-2219+49.3
=-2169.7
