the old four 4s are ....

this puzzle was given to us by our maths teach eons ago. basically you have four 4s, and you can arrange them in any way using mathematical symbols (+,-,! ^ sqrt) so that the result in an integer.

it is possible to do all integers from 0 to 100 and probably higher.

0 = 4 + 4 - 4 - 4
1 = (4 + 4 )/(4+4)
2 = (4 * 4)/(4+4)
3 = (4 + 4 + 4)/4

etc.
100 = 44/.44

i have a good maths puzzle.

in my job i have to correspond with a lot of solicitors. one of them wrote a snarky letter pointing out that our charity wasn't entitled to a 1/5th share of a deceased's residue, we were entitled to a 1/4 share of 80% of the residue as they had clearly stated in their letter.

i look forward to writing the reply.

Why?

My old maths teacher used to tell us about how during his national service he used to produce magic squares for a bet. Telling us about it years later, he said he felt guilty because the people placing bets that he couldn't come up with a magic square for the number they supplied to him weren't bright enough to realise all his solutions were concocted from just a few well known magic squares.

Well, in support of my ex-colleagues, I can see why their letter might have been strictly correct. If the Will had said, for instance, "I leave one fifth of my residuary estate to A and four fifths to be divided equally between the children of B", with B having four surviving children, your result would have been the same as theirs but your method of calculation would have been wrong.

ah, but the 1/4 of 80% in the Will was strictly defined as being between 4 charities.. the other 20% was gifted to private beneficiaries with no substitution for the charity beneficiaries should any of these fail. so whatever the outcome, the charities will receive 20% or 1/5.

the solicitor actually underlined the share amount in their letter too. they are scottish, so it may be a factor.
