答案： 解析：本题考查的是小数的加减法运算。
答案如下：
$0.36 + 3.6 = 3.96$
$0.36 + 0.06 = 0.42$
$0.36 + 6 = 6.36$
$0 + 0.36 = 0.36$
$0.36 - 0.36 = 0$
$0.36 - 0.16 = 0.2$
$0.36 - 0.06 = 0.3$
$0.36 - 0 = 0.36$
$2.47 - 0.07 = 2.4$
$2.47 - 0.47 = 2$
$2.47 + 0.07 = 2.54$
$2.47 + 0.7 = 3.17$
$2.47 + 7 = 9.47$
$2.47 + 0.4 = 2.87$
$2.47 - 2 = 0.47$
$2.47 - 0.4 = 2.07$
$2.47 - 2.47 = 0$
$7.4 - 0.4 = 7$
$7.4 - 4 = 3.4$
$7.4 - 4.4 = 3$
$0.25 + 1 = 1.25$
$0.25 + 1.05 = 1.3$
$0.25 + 10 = 10.25$
$0.25 + 0.2 = 0.45$
$0.25 + 0.05 = 0.3$
$2 - 0.25 = 1.75$
$10 - 0.25 = 9.75$
$8 - 0.25 = 7.75$
$0.25 - 0.25 = 0$
$0.25 - 0.05 = 0.2$
$0.25 - 0.2 = 0.05$
$4.73 - 4 = 0.73$
$4.73 - 0.73 = 4$
$4.73 - 0.03 = 4.7$
$4.73 - 0.7 = 4.03$
$4.73 - 4.7 = 0.03$
$4.73 - 4.73 = 0$
$8.65 - 1 = 7.65$
$8.65 - 0.6 = 8.05$
$8.65 - 0.65 = 8$
