In these problems, the integers 1,2,3,4,5,6,7,8,9 appear each exactly once, in such a way that the equations are correct, with the usual convention that multiplication and division are performed before addition and subtraction. Otherwise, as usual the evaluation is from left to right. For example a-b-c is (a-b)-c NOT a-(b-c).

This kind of problems appear in the Australian daily newspaper "The Australian".
