Q. 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?

• 4*5=20, 9=6=3, 7+1=8
