Puzzled hasn't got back to me but maybe you will take up my challenge Zamarroncis.

This is a difficult logic game if you want to really test yourself.

Another day and all questions are answered.

There were sum fantastic answers today from Doc, Zamarroncis, Gene, and Sp3ctr3.
Thanks guys - that's fabulous.

Doc, I would like you to go back to the divisability post and reply with some examples of what you meant.
Some people wont understand if you don't illustrate what you mean with an example or two.

Ok So what do we have so far,

1) we have Zamarronics's formula,

2) A number is exactly divisable by 10 if it has a zero at the end. (the last digit is zero)

3) A number is exactly divisable by 2 if it is even.

4) If a number is prime then it is only exactly divisable by 1 and itself

5) A number is exactly divisable by 5 if it ends in 0 or 5

6) A number is exactly divisable by 3 if the sum of its digits is exactly divisable by 3.

Doc, perhaps you could add a little to this one, it needs a couple of examples because people might not know what you mean.

Guest:
if the vertex angle of an isosceles triangle measure 46 degrees, what is the measure of its base angles?

Well, the base angles are the same so they could each be x then the other one is 46 degrees and , let me see, what was the angle sum of a triangle?
Mmm maybe I could google it. Mmm I could add up all the angles and that's what they would be equal to, then I could set up and solve a little equation.
YES That would work! Arn't i clever ?

Try to do it now and if you can't post back with what you have , or with your answer
