1. ## Simple Maths

How many answers to the following can you get (anything goes as long as you can supply a reason for your answer)
<pre>| + | =</pre>

2. ## Re: Simple Maths

I would say:
<span style="background-color: #FFFF00; color: #000000; font-weight: bold"><font color=yellow>1 answer: 2*|

or

an infinite number of answers: 1 for each "|"</font color=yellow></span hi>

The obvious answer is 11 (binary)

Also 42 (the answer to everything)

Cant think of another just yet

4. ## Re: Simple Maths

Actually, wouldn't that be 10 binary?

This is a simple puzzle we use to use at school a lot, mainly because it had two trick answers. The answers were ... 41 and 'a window'

<span style="background-color: #FFFF00; color: #000000; font-weight: bold"><font color=yellow>1.99999999999999999999999999999999999 999999999......................................... .....</font color=yellow></span hi>

And here's the proof:

<span style="background-color: #FFFF00; color: #000000; font-weight: bold"><font color=yellow>x=.999999999.............
therefore 10x=9.999999999999999999999999..........
subtract the equations:
9x=9
divide by 9 on both sides
x=1
Therefore, 1=.9999999999999................
thus 1+1=1.9999999999999999999999........
</font color=yellow></span hi>

Which presents at least one more 'trick' answer, which would be a <span style="background-color: #FFFF00; color: #000000; font-weight: bold"><font color=yellow>doughnut and coffee</font color=yellow></span hi>
