答案： 解析：
这些问题都是基础的数学运算，包括乘法和加减法。我们只需要依次计算每个表达式的结果即可。
答案：
$6.5 × 5 = 32.5$；
$6.5 + 5 = 11.5$；
$6.5 - 5 = 1.5$；
$3.3 × 3 = 9.9$；
$3.3 + 3 = 6.3$；
$3.3 - 3 = 0.3$；
$12.5 × 8 = 100$；
$12.5 + 8 = 20.5$；
$12.5 - 8 = 4.5$；
$4 × 0.36 = 1.44$；
$4 + 0.36 = 4.36$；
$4 - 0.36 = 3.64$；
$1.8 × 0.4 = 0.72$；
$1.8 + 0.4 = 2.2$；
$1.8 - 0.4 = 1.4$；
$7.6 × 0.01 = 0.076$；
$7.6 + 0.01 = 7.61$；
$7.6 - 0.01 = 7.59$；
$5.7 × 0.06 = 0.342$；
$5.7 + 0.06 = 5.76$；
$5.7 - 0.06 = 5.64$。

$7.2×0.1×0.1=$0.072
