61+5×610+49×61简便计算61+5×610+49×61简便计算61+5×610+49×61简便计算61+5×610+49×61=61x(1+50+49)=61x100=610061+5x61

61+5×610+49×61简便计算
61+5×610+49×61简便计算

61+5×610+49×61简便计算
61+5×610+49×61
=61x(1+50+49)
=61x100
=6100

61+5x610+49x61
=61+50x61+49x61
=(1+50+49)x61
=100x61
=6100

一个61加50个61再加49个61等于100个61 也就是6100

61+5×610+49×61
=61+61×50+61×49
=61×(1+50+49)
=61×100
=6100

61+5×610+49×61=61+50×61+49×61=61×(1+50+49)=100×61=6100

这道题目的共同点是每个加数都是61的倍数,利用结合律提取61,则
61+5×610+49×61
=61x(1+50+49)
=61x100
=6100

=1X61+5x10X61+49X61
=(1+50+49)X61
=100X61
=6100
