The object of this puzzle is to place arithmetical signs between the numbers so as to produce the answer given when the sum is done correctly. You must not alter the order of the numbers. Can you find a solution that uses the fewest possible signs and secondly an answer that requires the fewest possible stokes of the pencil or pen (eg.- is one, + is two,÷ is three,x is two , a bracket counts as two strokes)
