85.5x2345-85.4x1345
=(85.4+0.1)x2345-85.4x1345
=85.4x2345-85.4x1345+0.1x2345
=(2345-1345)x85.4+234.5
=1000x85.4+234.5
=85400+234.5
=85634.5

85.5x2345-85.4x1345
=85.5x2345-85.5x1345+0.1×1345
=85.5×（2345-1345）+134.5
=85.5×1000+134.5
=85500 +134.5
=85634.5
=85.5x2345-85.5x1345+0.1×1345
=85.5×（2345-1345）+134.5
=85.5×1000+134.5
=85500 +134.5
=85634.5
