Пошаговое объяснение:

20*713*5 = (20 * 5) * 713 = 100 * 713 = 71300

(100+5)*7= (100 * 7) + 5 * 7 = 700 + 35 = 735

2*(100-4) = (2 * 100) - 2 * 4 = 200 - 8 = 192

5*(200-2) = (5 * 200) - 5 * 2 = 1000 - 10 = 990

must have done all right because after half an hour’s wait I was sent into another room for a
psychological test. The examiner sat at a desk. You were signaled forward to occupy the seat
opposite him when the previous occupant had been 4________.
Sometimes the person was rejected quickly and sometimes after quite a while. Obviously the
longer interviews were the most successful ones. Mine was the only one that lasted a minute and a
half. I can remember the questions now: “Why did you leave your last job, “Why did you leave
your job before that? “And the one before?”
I can’t 5_______ my answers, except they were short at first and grew shorter as we

psychologist he had risen no higher than the underground railway. “You have failed this test and we
are unable to offer you a position.” Failing to get that job was my low point. Or so I thought,
believing that the work was easy. Actually, such a job 7________exactly this sort of elementary
responsibility a dreamer like me is unlikely to have. But, I was still far short of self-understanding
as well as short of cash.
