照样子写算式? 一年级数学照样子写数

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)
