If A*B is the greatest common factor of A and B, A$B is defined as the least common multiple of A
and B, and (A intersection B) is defined as equal to (A*B) $ (A$B), then what is the value of (12 intersection 15)?
How would you solve this? Are there any tips you have for solvning defined functions?[/list]

First you need to expand each of the brackets:
(A*B) = (12*15) = 3 (3 is the greatest common factor of 12 and 15)
(A$B) = (12$15) = 60 (60 is the least common multiple of 12 and 15)
>(A*B) $ (A$B),
= 3 $ 60 = Least common multiple of 3 and 60 = 60
(A*B) = (12*15) = 3 (3 is the greatest common factor of 12 and 15)
(A$B) = (12$15) = 60 (60 is the least common multiple of 12 and 15)
>(A*B) $ (A$B),
= 3 $ 60 = Least common multiple of 3 and 60 = 60

But what does the dollar sign ($) mean?

Nothing, its just a symbol to represent a mathematical operation... you can replace it with whatever you like.andre.heggli wrote:kmittal82 wrote:First you need to expand each of the brackets:
