67×25×3+67×25的简便运算，列一下竖式，谢谢

Answer 1

先运用乘法结合律，再运用乘法分配律。
67×25×3+67×25
=67×（25×3）+67×25
=67×75+67×25
=67×（75+25）
=67×100
=6700

Answer 2

这个题目用不着竖式，简便计算过程如下：
67*25*3+67*25
＝67*25*(3+1)
＝67*25*4
＝67*100
＝6700

Answer 3

67×25×3+67×25
=67×(25×3+25)
=67×100
=6700

Answer 4

67x25x3+67x25
=67x25x（3+1）
=67x25x4
=67x（25x4）
=67x100
=6700

Answer 5

67×25×3+67×25
=67×25×（3+1）
=67×25×4=6700
