将相邻两数之差小于 20 的两个数圈起来(可以左右圈,也可以上下圈)

答案

2,6,5,4,4,6,5,0,7,4,9,9,3,3,9,4,9,9,8,1,0;=,<,<,=,>,<;圈出(24,9),(15,9),(40,25),(3,9),(42,24),(24,6),(38,20),(20,7)。

解析

1. $36 - 16 = 20$,□填2;$52 - 6 = 46$,□填6;$57 + 5 = 62$,□填5;$36 + 6 = 42$,□填4;$76 - 12 = 64$,□填4;$74 - 6 = 68$,□填6;$36 + 16 = 52$,□填5;$53 - 13 = 40$,□填0;$74 + 7 = 81$,□填7;$46 - 4 = 42$,□填4;$66 - 7 = 59$,□填9;$51 + 9 = 60$,□填9;$43 - 7 = 36$,□填3;$14 + 9 = 23$,□填3;$67 - 9 = 58$,□填9;$51 - 9 = 42$,□填4;$54 - 5 = 49$,□填9;$14 + 9 = 23$,□填9;$90 - 8 = 82$,□填8;$37 - 6 = 31$,□填1;$90 - 10 = 80$,□填0。
2. $58 + 17 = 17 + 58$;$32 - 18 < 32 + 18$;$3 + 80 < 30 + 80$;$65 + 9 = 69 + 5$;$90 - 9 > 90 - 19$;$74 - 9 < 79 - 4$。
3. 圈出相邻两数差小于20的数对:(24,9),(15,9),(40,25),(3,9),(42,24),(24,6),(38,20),(20,7)。
