e pluribus unum ii (Posted on 2004-01-22)

Below are three groups of three numbers each. Combine the numbers in each group using the standard binary operations (addition, subtraction, multiplication, division, and exponentiation) so that each group yields the same number.

3, 15, 18
10, 13, 36
24, 27, 39

For an example, see the first problem.

18-(15/3) = 13
36-(10+13) = 13
39/(27-24) = 13
