Fibonacci sequence works well below zero too. Here is the sequence -8,5,-3,2,-1,1,0,1,1,2,3,5,8,13,… T he sequence below zero has the same numbers as the sequence above zero,  except they follow a +-+- ... pattern.

       FACTORIAL   !   The factorial of a positive integer n , denoted by n! , is the product of all positive integers less than or equal to 1.     For example the factorial of 6 is 6! = 6*5*4*3*2*1 = 720 The value of 0! is 1 , according to the convention for an empty product. We can calculate a factorial of a number(n)  from the previous one i.e. by multiplying the number (n)  to a factorial of number(n-1) . n! = n * (n-1)! For example: 5! = 5*4*3*2*1 = 120 . So calculate the factorial of 6 by above rule. 6! = 6 * (6-1)! = 6 * 5!= 6 * 120 = 720 7! = 7 * (7-1)! = 7 * 6!= 7 * 720 = 5040 To see the working of flowchart,  Click here to watch on YouTube To write the program in C,  Click here to watch on YouTube To Create the Factorial App in MIT App Inventor  Click here to watch on YouTube Download the Factorial Android App here Factorial Android App
