7 - 3 = 6 - 0 = 9 - 8 + 2 =
4 + 6 = 11 + 6 = 12 - 2 + 4 =
8 + 10 = 5 - 5 = 3 + 7 + 8 =
12 + 6 = 3 + 4 = 10 - 6 - 4 =
5 + 4 = 8 - 6 = 12 - 10 + 8 =
18 - 5 = 4 - 0 = 14 - 4 - 3 =
10 - 6 = 3 + 7 = 5 + 13 - 10 =
17 - 7 = 15 - 4 = 6 + 4 + 2 =
16 - 1 = 10 + 7 = 10 - 7 + 10 =
8 - 4 = 19 - 10 = 4 + 3 - 1 =
7 - 3 = 6 - 0 = 9 - 8 + 2 =
4 + 6 = 11 + 6 = 12 - 2 + 4 =
8 + 10 = 5 - 5 = 3 + 7 + 8 =
12 + 6 = 3 + 4 = 10 - 6 - 4 =
5 + 4 = 8 - 6 = 12 - 10 + 8 =
18 - 5 = 4 - 0 = 14 - 4 - 3 =
10 - 6 = 3 + 7 = 5 + 13 - 10 =
17 - 7 = 15 - 4 = 6 + 4 + 2 =
16 - 1 = 10 + 7 = 10 - 7 + 10 =
8 - 4 = 19 - 10 = 4 + 3 - 1 =
答案:
4 6 3 10 17 14 18 0 18 18 7 0 9 2 10 13 4 7 4 10 8 10 11 12 15 17 13 4 9 6
二、在$◯$里填“$>$”“$<$”或“$=$”。(每题2分,共18分)
11 - 10$◯$7 14$◯$13 + 1 10 + 9$◯$9 + 10
2 + 3$◯$6 17$◯$9 + 1 + 5 10 + 2$◯$13 - 3
19 - 5$◯$13 12$◯$16 - 3 12 + 2$◯$11 + 4
11 - 10$◯$7 14$◯$13 + 1 10 + 9$◯$9 + 10
2 + 3$◯$6 17$◯$9 + 1 + 5 10 + 2$◯$13 - 3
19 - 5$◯$13 12$◯$16 - 3 12 + 2$◯$11 + 4
答案:
< = = < > > > < <
三、在$□$里填合适的数。(每式2分,共12分)
5 + $□$ = 4 + 3 7 + 3 - $□$ = 5 14 - 4 - $□$ = 2
9 + 1 = $□$ + 6 4 + $□$ + 2 = 10 3 + $□$ + 5 = 15
5 + $□$ = 4 + 3 7 + 3 - $□$ = 5 14 - 4 - $□$ = 2
9 + 1 = $□$ + 6 4 + $□$ + 2 = 10 3 + $□$ + 5 = 15
答案:
2 5 8 4 4 7
