照样子写算式? 一年级数学照样子写数
脑筋题目:照样子写算式5
这个算式结果太多了,符号的组合就有256种,这个不准备计算了,3个符号的使用计算机计算了一个小时,结果是:post.baidu/f?kz=111036661
4个符号的计算量也是巨大的。
计算了一种??×??÷??×?-?=??,共有240个结果:

照样子写算式
29÷4=7……1 29-1=28 28/4=7 29+3=32 32/4=8
35÷8=4……3 35-3=32 32/8=4 35+5=40 40/8=5
50÷6=8……2 50-2=48 48/6=8 50+4=54 54/6=9
照样子写算式:
29÷4=7……1 29-1=28 (28÷4=7 ) (29+3=32 ) (32÷4=8 )
35÷8=4……3 (35-3=32 ) ( 32÷8=4 ) (35+5=40 ) (40÷8=5 )
50÷6=8……2 (50-2=48 ) (48÷6=8 ) (50+4=54 ) ( 54÷6=9 )
照样子照样子接着写算式并算一算,你发现了什么,202×9,等于,1818606乘几?
202×9=(1818)
1818606=(3001x6)或者(202x9003)
