[SOLVED] expressions of integers
Let n be a positive integer. How many ways can you express a as the sum of positive integers? Order of addition does not matter.
EDIT: change "a" to "n" in the second sentence
Let f(x) be the function that gives the number of ways you can express x as the sum of positive integers? Order of addition does not matter.
f(1)=1
f(2)=2
f(3)=3
f(4)=5
f(5)=7
I do not see the pattern. I was hoping for Fibonacci numbers...
