英語笑話：數(shù)學(xué)教授

A math professor has just been knocked down by a speeding car. A police officer rushed over and asked，"Were you able to get the license number of the vehicle that hit you，sir?”

一位數(shù)學(xué)教授被一倆時速很快的車撞倒了。警察跑過去問:“先生，您能說出撞您的那輛車的車牌號碼嗎?”

The professor replied，"Well，not exactly，but I do recall that if the number was multiplied by itself，then divided by three，the square root of the answer would turn out to be the original number with the integers reversed.”

教授回答:“嗯，我說不準，可是我記得，如果將號碼自乘，再除以三，然后開方，則平方根正好同原數(shù)的次序顛倒過來。”
