If you think about it, the division in the permutation is also a consolidation. At first, you take all n items and put them in the sequence. This can be done n! ways. But then you realize that you are interested in the first (or last) k items only, so you consolidate the reordering of the remaining n-k items. That is the division by (n-k)!.

Imagine if maths is taught like this – motivate from simple, known perspective to abstract generalization- the world will be richer than it is; because more things would have been discovered, invented by people who today are permanently excluded because of very dry, not-inspiring way maths is being taught. See the way Kalid presented maths thoughts, ideas and reasoning simply, immediately making sense and retaining their profundity. Thank you Kalid

This site is completely amazing!
Cheers to the author!
I was going through some hard time with calc, but now everything looks so much better. Right now as I focus on calc I can feel some of the voids I have from previous subjects like trig, and I can’t wait to see what you have in the site for that subject!
At first I thought it was going to be one of those”freemium” sites that promise everything after you bought the whole thing, but better explained gives you the whole thing for free. However, It’s been so satisfactory until now that I will no doubt pay for the whole course, specially to get access to the discussion sections!
Thanks man, you are saving not only my calc course, but probably my whole career with this approach!
