A lawyer, an engineer and a mathematician were called in for a test. The engineer went in first and was asked, “What is 2+2?” The engineer thought awhile and finally answered, “4.” Then the mathematician was called in and was asked the same question. With little thought he replied, “4.0.” Then the lawyer was called in, and was asked the same question. The lawyer answered even quicker than the mathematician, “What do you want it to be?”
一個(gè)律師、一個(gè)工程師和一個(gè)數(shù)學(xué)家被叫來參加一項(xiàng)考試。工程師第一個(gè)進(jìn)來。問他的問題是“二加二等于幾?”工程師想了一會(huì)兒,最后說:“等于四?!苯又?,數(shù)學(xué)家被叫進(jìn)來,問同一個(gè)問題。他想也不想就回答說“等于四點(diǎn)零”。最后,律師被叫進(jìn)來,問同一個(gè)問題。他甚至比數(shù)學(xué)家回答得還要快:“你想要它等于幾?”
