More than one way to skin a cat (Posted on 2010-03-24) Difficulty: 2 of 5
You start with a zero and try to reach exactly 100 in 4 stages, each stage consisting of either increasing or decreasing your current number by a factorial n!( number like 1,2,6,24,120,720 etc) .
How many sequences exist to accomplish this task?

Good beginning.
The total number is much more than 12.
Carry on!
