    a = 17
    b = 0

    17.0 + 17 + 0 = 34

    why is that the only answer?
    b needs to be 0 because otherwise the sum would have a decimal in it. since 34 is an integer, we cannot have that.

    That is nonsense!
    a = 4\,\& \,b = 6
    (4)(6)+(4)+(6)=34

    No, I cannot explain how I solved the problem!
    First assume that we are dealing with natural numbers (positive).
    I just know a great deal about how numbers work.
    It does not take much to see that the integers must be less that ten.
    It was simple to try various combinations.

    Read Dubulus' response. He was interpreting the "." in "a.b" as a decimal point. Certainly 17.0 is the same as 17.

    I thought it was a pretty good joke at first!
