答案
1. ＞ ＜ ＜ ＞ = ＜ ＜
2. 填一填。
$□$ + 7 = 13
8 + $□$ = 15
9 + $□$ = 25 - 11
47 - $□$ = 22
$□$ - 14 = 36
23 + 34 = 62 - $□$
$□$ + 16 = 54
$□$ + 27 = 76
41 - 6 + $□$ = 60
$□$ + 7 = 13
8 + $□$ = 15
9 + $□$ = 25 - 11
47 - $□$ = 22
$□$ - 14 = 36
23 + 34 = 62 - $□$
$□$ + 16 = 54
$□$ + 27 = 76
41 - 6 + $□$ = 60
