1.83×1.7-1.83×0.4-1.83×0.03怎么简便计算

Answer 1

1.83×1.7-1.83×0.4-1.83×0.03
=1.83×(1.7-0.4-0.03)
=1.83x(1.3-0.03)
=1.83x1.27
=1.83x(1+0.2+0.07)
=1.83+0.366+0.1281
=2.196+0.1281
=2.3241

Answer 2

1.83×1.7-1.83×0.4-1.83×0.03=1.83×(1.7-0.4-0.03）=1.83×1.27=1.83×1+1.83×0.2+1.83×0.07
=1.83+0.366+0.1281
=2.196+0.1281
=2.3241
