Question

15.01➕1.99✖️1.6等于多少？

答案

Answer 1

通过观察，我们进行数据变换后进行简便运算
15.01+1.99*1.6
=15.01+(1.99+0.01)*1.6-0.01*1.6
=15.01+2*1.6-0.016
=15.01*3.2-0.016
=18.21-0.016
=18.194

Answer 2

15.01+1.99*1.6=18.194 希望能够帮助上您

Answer 3

15.01+1.99×1.6=18.194
把1.99看成2-0.01
用15.01+(2-0.01)×1.6
=15.01+3.2-0.06=18.15
所以最后结果18.15

Answer 4

15.01+1.99*1.6
=15.01+（2-0.01）*1.6
=15.01+2*1.6-0.01*1.6
=15.01+3.2-0.016
=15.01+3.184
=18.194

Answer 5

15.01+1.99x1.6
=15.01+3.184
=18.194
