I want to climb down a flight of ten stairs, taking one or many steps at a time. In how many ways can I do this if I am able to take as many steps at a time as I like?
I don't know the answer; I am getting $3$ such as:
$1,2,3,4,..., 10$ (one at a time)
$2,4,6,..., 10$ (two at a time)
$5,10 $ (five at a time)
this is correct/incorrect?
