section 10.4

• Read everything but you can skip the investigation
• Uber important! understand the definition of permutation and combination! This is ridiculously important!
• Read and reread if necessary 
• example A - permutation
• example B - permutation
• example C - combination
• Understand the notation nPr and nCr. Your calculator can do these calculations (of course) I'll show you how, but I also want you to understand how to do it using "symbolic manipulation". It is an excellent example of "reduce before you multiply".
