Maths problem

[Iain]

For all th4e budding engineers and mathematicians figure this one out.
Use exactly four 9s and any number of arithmathic or higher level math operations to make numbers from 1 to 20.
Example
1=(9+9)/(9+9)
7=(9+9+sqrt9)/(sqrt9)

[Wongo]

Iain,

Although I think that the “square root” operation does not meet the conditions (it is equivalent to the power of ½ and we can only use 9s), otherwise here is my attempt.

Some people have to much time on their hands?

Clever buggers. Maths was never my forte.

[DaveInOz]

Hey Wongo, wanna do my tax for me?

[Zed]

is the word "geek" or "nerd" more appropriate here ?

calculators and spreadsheets do it for me....

[DaveInOz]

Careful Zed, concentrate on what your doing rather than try to pull down your mental superiors. Remember one slip of the saw and you'll only be able to count to 9.

It reminds me of most of the maths they made us do in high school. All very interesting but difficult to see what possible use it is to anyone

[Wongo]

Not a lot but it is fun

[silentC]

Wongo mate, I can see that I am going to have to sit you down and explain the meaning of the word 'fun' to you.

Messing about with wood 'n stuff in your shed is fun.
Playing cricket in your backyard with a lump of 4x2 and a tennis ball is fun.
Chatting up some bird at the pub you have no chance with is fun (although getting sprung by your wife is NOT fun).
Swimming in the ocean is fun.
Riding a motorbike is fun.

Maths, in any shape or form, is NOT, repeat, NOT fun.

Now get out there and have fun, Professor Frink.

[DaveInOz]

SilentC,
You forgot baiting people, especially on BBs, or is that just fun for bastards like me.

[silentC]

shhh, Dave, you'll give the game away...

[Sturdee]

Darren,

Untill recently I used to do number crunching for a living and I enjoyed it. In fact I always thought I had fun whilst working ( except on " ladies" days of the golf club I used to work ) so what do I do now.

Peter.

[silentC]

Peter,

I'm sorry, but I think you're a lost cause mate!!

[Zed]

please see my previous post.
:confused:

Nicely done Wongo,

I don't see any reply from Ian here, he probably doesn't know the answer.

Of course I don't have any idea either


Ben.
