答案： 解析：这些题目都是基础的加减法运算，考察的是速算能力。对于每一组算式，我们可以直接通过加减法运算来找出缺失的数字。
答案：
$41 + 52 = 93$，$32 + (42) = 74$
$12 + 20 = 32$，$(35) + 62 = 97$
$76 + 20 = 96$，$29 + (22) = 51$
$29 + 37 = 66$，$83 - (21) = 62$
$66 + 18 = 84$，$55 - (18) = 37$
$38 + 18 = 56$，$(84) - 22 = 62$
$37 + 25 = 62$，$28 + (24) = 52$
$47 - 19 = 28$，$(35) + 35 = 70$
$58 - 5 = 53$，$60 - (31) = 29$
$76 - 27 = 49$，$84 - (36) = 48$
$34 - 15 = 19$，$(27) + 45 = 72$
$53 - 24 = 29$，$(97) - 33 = 64$
$76 - 29 = 47$，$30 + (39) = 69$
$49 + 35 = 84$，$(28) + 55 = 83$
