1 2 3 4 5 6 7 8 9 = 100.

It is required to place arithmetical signs between the nine figures so

that they shall equal 100. Of course, you must not alter the present

numerical arrangement of the figures. Can you give a correct solution

that employs (1) the fewest possible signs, and (2) the fewest possible

separate strokes or dots of the pen? That is, it is necessary to use as

few signs as possible, and those signs should be of the simplest form.

The signs of addition and multiplication (+ and x) will thus count as

two strokes, the sign of subtraction (-) as one stroke, the sign of

division (/) as three, and so on.
