A mathematician, an accountant and an economist apply for the same job. The interviewer calls in the mathematician andasks "What do two plus two equal?"
The mathematician replies "Four."The interviewer asks "Four, exactly?"The mathematician looks at the interviewer incredulously andsays "Yes, four, exactly."
Then the interviewer calls in the accountant and asks the samequestion: "What do two plus two equal?"The accountant says, "On average, four -- give or take 10%,but on average, four."
Then the interviewer calls in the economist and poses the same question: "What do two plus two equal?"The economist gets up, locks the door, closes the shade, sitsdown next to the interviewer, and says, "What do you want it to equal?"

engineers would reply thus: Of course, as you are well aware, two plus two equals five (for large values oftwo) or even three (for small values of two). "Two," given as it is to just one significant figure (it was described as neither exact nor integral), can take any value in the range [1.5, 2.5) where the right hand limit is open.

Profession joke, oky
