4.65*32+25(2.5)*46.5+0.465*430
4.65*32+2.5*46.5+0.465*430
=4.65*32+25*4.65+4.65*43
=4.65*(32+25+43)
=4.65*100
=465
43.56*132.7-4.357*327
=4.356*1327-4.357*327
=4.356*(1000+327)-4.357*327
=4.356*1000+4.536*327-4.357*327
=4356+(4.536-4.537)*327
=4356-0.001*327
=4356-0.327
=4355.673
4.65*32+2.5*46.5+0.465*430
=4.65*32+25*4.65+4.65*43
=4.65*(32+25+43)
=4.65*100
=465
