17.9×9.9+17.9+0.1
=17.9×(9.9+1)+0.1
=17.9×10.9+0.1
=17.9×(10+0.9)+0.1
=17.9×10+17.9×0.9+0.1
=179+17.9×(1-0.1)+0.1
=179+17.9×1-17.9×0.1+0.1
=179+17.9-1.79+0.1
=195.21
=17.9×(9.9+1)+0.1
=17.9×10.9+0.1
=17.9×(10+0.9)+0.1
=17.9×10+17.9×0.9+0.1
=179+17.9×(1-0.1)+0.1
=179+17.9×1-17.9×0.1+0.1
=179+17.9-1.79+0.1
=195.21
