The reason why 0! Equals 1 is because when you do 0!= 1!/1! (One factorial over one factorial) it just cancels out to 1. It’s the same if you were to do 2!=3!/3!. When you expand the equation, You would cancel out the 3 on the bottom with the three on the top and be left with 2 times 1 which, of course, is 2!

I love how he explains the difference between permutation and combination. It took a me a couple example to finally grasp the advantage of using the formula provided. Not only it made bigger equations to solve but instead of drawing them out which could take longer.

i've been struggling really badly in CIE additional mathematics for the past few months, mainly because i wasn't getting the hang of a few chapters, this one included. my ex math tutor introduced this chapter to me quite a long time ago, and today is the day i REALLY understood the concept, which is astonishing. i've always hated this chapter, because it seemed so confusing and incomprehensible. i tried reading the text book, that has even worse explanations, i went to my older sister, still didn't understand; and today i finally decided to go and check on the internet. i still wasn't getting it from trying a few channels and then i bumped into this guy. and im SO thankful, cause i cant believe i understood a concept that i've been struggling to grasp for MONTHS in a matter of 17 freaking minutes. dear organic chemistry tutor, if you're reading this, i want you to know that you're a hero. you have no idea how much of an immense help you were to me today, and to millions others. not all heroes wear capes, sometimes they run a youtube channel to help others out. keep up this amazing work!!

For anyone looking for an (in my opinion) an easier way to calculate the r-Permutations: P(n,r) For example: P(4,3)= 4x3x2 p(8,5)= 8x7x6x5x4 So the r is actually just the number of times you need to multiply down. So in the first example, we multiply down 3 times, where as in the second one we multiply 5 times. An easier way (in my opinion) to do the equation for r-Combination is: C(n,r) = P(n,r)/r! For Example: C(6,3) = P(6,3)/3! P(6,3) = 120 (6x5x4) 120 / 6 (3! = 3x2x1) C(6,3) = 120/6 = 20 A second example: C(7,2) = P(7,2)/2! P(7,2) = 42 (7x6) 42 / 2 (2! = 2x1) C(7,2) = 21 A third example: C(8,3) = P(8,3)/3! P(8,3) = 336 (8*7*6) 336/6 (3! = 3x2x1) C(8,3) = 56 Hope this helps.
