You don't understand it then - mathematical proof is mathematical proof is mathematical proof - there is no 'technically' about it - it is likely your mistaken assumption that a non zero real number has a unique decimal representation that is throwing you off - it is the same number just represented differently.
Post me your hardest maths question you know

The guy on the left made a $10 profit but the guy on the right paid $50
I don't think you quite understand infinity properley yourself.
Infinity is neither a number, time or an amount.
Meh...
a = b
a^2 = a*b
a^2-b^2 = a*b-b^2
(a+b)(a-b) = b(a-b)
(a+b) = b
a+a = a
2a = a
2 = 1
Yeah I know it's incorrect, just putting it out there.

(a+b)(a-b) = b(a-b)

2a = a

Such blasphemy...
Would someone kindly show him the door

I know you said you know it's incorrect but for anyone who is wondering why it is
a = b
a - b = 0
a
and so when you divide the factor of (a-b) out you are dividing by zero. naughty naughty.
what is the square root of -0.9r
plus or minus (0.9r)i
which in its simplest form is plus or minus i
Here is a very hard problem that doesn't require any advanced mathematical techniques to solve, just a huuuuge brain!
There are N>3 gossiping women and each of them knows some item of gossip not known to the others. They talk to each other via the telephone and in each conversation they tell each other all they know at that point in time. What is the minimum number of phone calls required before each woman knows all the gossip.
Here is a simpler problem (still no advanced mathematics required):
I have a bowl containing 1000 strands of spaghetti. I pick two ends of spaghetti at random and tie them together, and I keep doing this until there are no more ends to grab. What is the expected number of loops in the bowl when I'm done?

I'll try desperately not to explode into a rant about 0.9r. Those with a long memory will remember my involvement with the first one....
Anyway.... Here's a vaguely accessible problem I had to solve today. 8 points in 3 dimensional space form a convex hull where all faces (of which there are 6) are convex quadrilaterals. What is the volume of the 3 dimensional hull? If you can't provide the explicit formula (and I don't blame you, its unpleasant) then provide the method by which you compute the volume and demonstrate it works for special cases like the hull being a regular cuboid. Extra points if your method work in any number of dimensions, not just 3 (though you'd be computing hyper-volumes obviously).

How many sandwiches can you make from 0.9r pieces of bread?
Afraid not (to both). The first one is particularly difficult - it is given to Cambridge 1st year undergraduates in their first couple of weeks and on average I think the stats are that about 1 student every 2-3years solves it.
