[speaker001:] What 's "pi"?
[speaker002:] That 's the ratio of the circumference of a circle to its diameter, I think.
[speaker001:] I see. What is that ratio exactly?
[speaker002:] It 's approximately 3.14, but the number continues forever. What 's the diameter of your circle?
[speaker001:] It 's 10 centimeters, so the circumference should be 31.4 centimeters.
[speaker002:] Ok. My next problem is to convert 10000 british pounds into us dollars. What 's the exchange rate at the moment?
[speaker001:] According to the newspaper, the exchange rate is 1.85 dollars to the pound.
[speaker002:] That means that 10.000 pounds will buy me 18.500 dollars.
[speaker001:] What 's the next question.
[speaker002:] Fractions. What 's a quarter and an eighth? That 's three-eights. Easy. The next question is "what are prime numbers?".
[speaker001:] I can help you there. Those are numbers that cannot be created by multiplying two whole numbers, apart from the number itself and 1, together.
[speaker002:] So, 1,2 and 3 are prime numbers, but 4 isn 't because 2 * 2 4.
[speaker001:] Exactly. Anything else?
[speaker002:] How many seconds in an hour? 60 seconds multiplied by 60 minutes equals 3600 seconds altogether.
[speaker001:] You 'll be a mathematician one day.
