QUIZ: Weakest Link
- Thread starter prunster
- Start date
for this to be true a would have to be 0 ?
so 2a = a
2x0 = 0
which is correct .. or maybe I am reading it wrong
A very smart Nicholas!
Yep zero works.
Steve
Yep zero works.

An Answer
What comes next in this sequence:
Iron Bromine Uranium Argon ==?==
Fe__Br_____U______Ar______?
? = Y (February)
Anyone know the name of the element Y ??
AND,
Has nobody worked this one out yet??
Perchance, do I have the expert panel stumped?!!
a = 9.999999...
10a = 99.999999...
10a - a = 90
9a = 90
a = 10
How can this be??????????????????????
Regards,
Steve
PS: One would think our very smart moderators could work this out in their sleep

Oh boy, Steve, you really know how to get a bloke moving ...

Steve, dunno what your official answer might say, but this one stems from the fact that we are multiplying a repeating number.
e.g. to help with the understanding, if we multiplied by 1,000,000 rather than by 10, what's happening is magnified somewhat, and becomes understandable.....
and that is:- by multiplying by such a huge number, we move everything 6 places to the left, but, because it is repeating, we DON'T drop 6 places off the right hand end of things !!!
This leads to the anomaly you have shown. Now, I didn't do University maths - perhaps one who has will have a more graceful way of explaining it than I do. But, I KNOW what you've done ........ and it's CHEATING
