Arrange the ten digits 0 to 9 in three arithmetical sums, using three of the
four operations of addition, subtraction, multiplication, and division, and
using no signs except the ordinary ones implying those operations. Here is
an example to make it quite clear:
3 + 4 = 7 9 - 8 =
1 5 X 6 = 30
But, the example is not correct, as the number 2 has not been used and the
number 3 has been used twice. Can you come up with a valid solution?
