Hey guys, It's me Brian Laderas..

Here is an example of permutations..
1.    Compute:  5 P 5         5 · 4 · 3 · 2 · 1  =  120
2.    Compute:         6 · 5  =  30                or                                          multiply by two factors
                                   of the factorial, starting with 6
3.    Find the number of ways to arrange 5 objects that are chosen from a set of 7 different objects.
        7 
P 5 =   7
·6·5·4·3  =  2520      or      
      
4.  What is the total number of possible 5-letter arrangements of the letters  w, h, i, t, e,  if each letter is used only once in each arrangement?  
          
P5   =   5·4·3·2·1   =   120     or           or    simply  5!
        
5.   How many different 3-digit numerals can be made from the digits  4, 5, 6, 7, 8   if a digit can appear just once in a numeral?
       
 P3  =   5·4·3  =  60            or
