By Ed, our maths studying friend.
You've probably clicked on this article expecting to find that it's really about
roleplaying. Bad luck. This article is being written to take the pressure off the
sensitive souls who write Critical Miss. You see, last issue Jonny introduced a
rating system which allows you, the readers, to let him know which articles are
good and which suck.
Unfortunately, someone has to come last, and Jonny felt that rather than
offend the creative talent, it would be better to have someone thickskinned
write a deliberately terrible article. So here it is. It's not even about roleplaying,
it's about maths. If you particularly hate maths you can give me a rating of 1
now and go read a more interesting article.
First of all, what is point nine recurring? Well, think about writing down a
fraction as a decimal. For example, you write a quarter as a decimal, you write
0.25. Other fractions can be a bit more troublesome. Trying to write a third as a
fraction you get 0.33333333... It never ends. Instead of writing down an infinite
number of 3s, it usually saves time to write down
which is said "zero point three recurring". Recurring means that instead of
terminating, the decimal continues indefinitely. Similarly, point nine recurring is
0.999999...
Looking at this number, most people think it is a little bit less than 1. In fact
they are the same. Let's take a look at why. Think about how we defined point
three recurring above.
What does this mean in English? It means that three times a third is one, and
three times point three recurring, which must be the same thing, is point nine
recurring, so one and point nine recurring must be the same number. Feel free
to use this explanation to look smarter than your friends if you ever get into an
argument about recurring numbers.
If you are not convinced by this, perhaps you would like to think about it
another way.
Translating this back to English, it means that nine times point nine recurring is
nine, which is the same as nine times one, so point nine recurring and one
must be the same.
I hope that at least one of these makes sense to you.
Now all that remains is for you to give this article a rating of point nine
recurring.
