推荐回答（5个）

回答1：

=186-12

=174直接算就非常的简单的。

回答2：

这道题可以简便运算，运用四则运算加法法则，先拆分取整，62可拆分为60+2，再用乘法分配定律计算。即：62*3-12=（60+2）*3-12=60*3+2*3-12=180+6-12=186-12=174 谢谢

回答3：

62×3-12
=62×3-2×3-6
=（62-2）×3-6
=60×3-6
=180-6
=174
谢谢你的提问，望采纳

回答4：

这道题直接从头开始算，没有什么简便计算方法。
62x3-12=186-12=174

回答5：

把12写成4X3，
62x3-12
=62X3一4X3
=（62-4）x3
=58X3
=(60-2)X3
=60x3一2x3
=180-6
=174
