7.536×99+75.36×0.1的简便算法
7.536×99+75.36×0.1的简便算法

7.536×99+75.36×0.1的简便算法
7.536×99+75.36×0.1
=75.36×9.9+75.36×0.1
=75.36×(9.9+0.1)
=75.36×10
=753.6

7.536×99+75.36×0.1
=7.536×(100-1)+7.536
=753.6-7.536+7.536
=753.6

=7.536×99+7.536×1=753.6

7.536×99+75.36×0.1=75.36x9.9+75.36x0.1=76.36x(9.9+0.1)=763.6
