Maths Solution

Problem expressed the other day. Use 5, 5, 5 and 1 to get 24.

If you multiply 5 by 5 and subtract 1 to the power 5 you get 24. I can't get this blog to do superscript so I apologise for the clunky expression of the solution.

My solution is slightly different, but I think correct. Subtract 1/5 (one fifth) from 5 giving you 4 4/5 (four and four fifths or 4.8 in decimals). Then multiply 4 4/5 by 5 giving the final answer of 24.

So, 5 x (5 - 1/5) = 24
