AWA:

AA 95 The following appeared as part of an article in the business section of a local newspaper.
“Hippocrene Plumbing Supply recently opened a wholesale outlet in the location once occupied by the Cumquat Cafe. Hippocrene has apparently been quite successful there because it is planning to open a large outlet in a nearby city. But the Cumquat Cafe, one year after moving to its new location, has seen its volume of business drop somewhat from the previous year’s. Clearly, the former site is a better business location, and the Cumquat Cafe has made a mistake in moving to its new address.”

You can tell the ideas of a nation by its advertisements.

Math:
1. PS 美国家庭92%的家庭拥有一台电视机, 60%的家庭拥有一台电视机和一台录像机,72%拥有一台电视机和一台DVD,问至少有多少家庭同时拥有一台电视机,一台录像机和一台DVD.(题目大概是这样)

答案中好象有26%, 32%, 34%.我瞎蒙了一个,还请高手指教算法.

2. PS X>0, Y, Z<0, 问(|X|+|Y|+|Z|)^2等于?

X^2+Y^2+Z^2-2XY-2XZ+YZ

3. PS (2^60-2^59)/2=?

2^58

又想起来一题.

4. 2^25被3除的余数是几?
