That’s Odd, i mean I know I definitely was taught what factorial meant before and im in calc 2 as well. No one had a problem with it that spoke up. I guess it just wasnt in your local curriculum?
I'm not in the school anymore but thanks to your videos I'm looking forward to learning maths just for fun. Everything you explain is logical and clear. You are the best teacher on the internet, thank you!
I swear this man is stalking me. He post inverse matrices while I'm learning about it in Linear algebra. He posts factorials when I'm reviewing the use of factorials in stats. wtf, why are you always here for me?
Why do professors have to make everything so complicated when it's this easy to explain? NOT saying your work is light, because you're literally carrying thousands of HS and college students through their courses but like...

majdalin, The reason school teachers don't explain like this guy is, the way math was taught when they were in school required memorization instead of understanding. The "solutions" weren't properly explained, and critical steps were left out. The students who received high grades were the ones who memorized the incomplete solutions that were written on the board.

I broke down factorial 52 so you can cheat on math homework Breaking down 52 factorial (52!) involves calculating the product of all positive integers from 1 to 52. It is an extremely large number, so let's take a look at the breakdown: 52! = 52 × 51 × 50 × 49 × ... × 3 × 2 × 1 To simplify the calculation, let's group some of the terms: 52! = (52 × 51 × 50 × 49 × ... × 3) × (2 × 1) Now, let's calculate the two parts separately: Part 1: (52 × 51 × 50 × 49 × ... × 3) This part involves multiplying all the numbers from 52 to 3. Part 2: (2 × 1) This part is simply multiplying 2 and 1. Calculating Part 1: 52 × 51 × 50 × 49 × ... × 3 = 3,041,409,320,171,337,804,361,135,652,208,989,321,781,688,343,680,000,000 So, Part 1 of 52! is equal to 3,041,409,320,171,337,804,361,135,652,208,989,321,781,688,343,680,000,000. Calculating Part 2: 2 × 1 = 2 So, Part 2 of 52! is equal to 2. Finally, we multiply Part 1 and Part 2 together to get the complete value of 52!: 52! = Part 1 × Part 2 = 3,041,409,320,171,337,804,361,135,652,208,989,321,781,688,343,680,000,000 × 2 And the result is: 52! = 6,082,818,640,342,675,608,722,271,304,417,978,642,816,780,000,000
Since when did math have punctuation? My textbook just randomly threw in an exclamation into a problem without explaining what it is. I thought is was an error at first. Then another appeared and then another... "Ok I give up, it's intentional." Let's just say I was pissed because I thought I missed a major section of the book. Thank goodness I have the internet. Thank you so much. Pfft, this reminds me of when I first learned about algebra.
Even if I was watching this in HS, I love the fact that he still chose to have our backs in the same video when I would have to now confront factorials with series
Hello sir. I'm leaving this comment here hoping you read it one day. I just wanted to let you know how LIFECHANGING these short videos are, my school randomly signed me up for a math contest, and I have to look into such topics that I've never even heard of before, and you have helped me SO MUCH!
Hi guys I have an ez question for u. 8! x 5 = ??? So, we have to know that the symbol {n!} is called a factorial. The factorial of 8= 8!= 40320 So first we do 8 x 7. Obvi 56!! Now 56 x 6 = 336! Now, 336 x 5 = 1680. Now we understand we have the product 1680. Now we do 1680 x 4. It’s 6720. We now do 6720 x 3. It’s 20160. Keep this in your mind for later use. Now we do 20160 x 2. Notice how it’s 40320? Yeah. Now multiply by 5. It’s surprisingly, 201600! Notice how Earlier 6720 x 3 is 20160? Cool right! Hope this helps :)
Why is the expression (n-1)!/n! = 1/n ? Because it makes me want to make so many different answers, I'm new to this. Examples as simplified 0/n or -1/n being that perenntacys are void with the adjustment of 1 null to being used before factorial.
Sir,I am a learning student, 1)12!÷6! This question answer is 665280 but 2)(12÷6)!this question trying to solve it but do not a success. sir what is the answer? please......
Thanks for explaining! I an really behind and math and have decided to do something useful on RUclips lol. Yeah, not motivated enough to do my work but I'll work on it. I know I really should just get working, because waiting for motivation ever works. But Imma just keep practicing math because my mom pays for classes but I feel like I'm falling behind in those as well and I'm not working hard enough. Enough of my rant though, thank you a lot! Your math videos are very motivating
A girl in my class is flexing her memorizing skills by doing 5x5, 10x10, 15x15 so on and so forth. I stepped up cause I am one of the best math students in my class and she left me off with a factorial which is 4!, I blatantly answered 2 even if it is wrong. I am watching this to completely demolish her spirit and be humble.
Watching you write out 4! * 3! made me realize that's also 4 * 3!², and then that 3!² is 3² * 2² which makes me think that k!^n = k^n * (k-1)^n * ... * 1
Ok... I want to understand why we are doing this not how, knowing the concept of things is the best way to understand math. You teach well, but I think you should make more videos explaining when these concepts are applicable and why we are actually doing this.
It turns out I'm not dumb. I understood the concept within 10 mins that the vid lasted, even though I couldn't get it within 45 minutes classes. I'm wasting so much time at school where I can't focus at all while I could simply study alone and know much more much faster.
Thank you so much for this! This is the first video I clicked on. My professor just threw this same factorial problem in the online lecture. I had no clue how he got 24 until now. :)

How do I find the base factorial (n) when given the solution (n!)
I broke down factorial 52 so you can cheat on math homework
Breaking down 52 factorial (52!) involves calculating the product of all positive integers from 1 to 52. It is an extremely large number, so let's take a look at the breakdown:
52! = 52 × 51 × 50 × 49 × ... × 3 × 2 × 1
To simplify the calculation, let's group some of the terms:
52! = (52 × 51 × 50 × 49 × ... × 3) × (2 × 1)
Now, let's calculate the two parts separately:
Part 1: (52 × 51 × 50 × 49 × ... × 3)
This part involves multiplying all the numbers from 52 to 3.
Part 2: (2 × 1)
This part is simply multiplying 2 and 1.
Calculating Part 1:
52 × 51 × 50 × 49 × ... × 3 = 3,041,409,320,171,337,804,361,135,652,208,989,321,781,688,343,680,000,000
So, Part 1 of 52! is equal to 3,041,409,320,171,337,804,361,135,652,208,989,321,781,688,343,680,000,000.
Calculating Part 2:
2 × 1 = 2
So, Part 2 of 52! is equal to 2.
Finally, we multiply Part 1 and Part 2 together to get the complete value of 52!:
52! = Part 1 × Part 2
= 3,041,409,320,171,337,804,361,135,652,208,989,321,781,688,343,680,000,000 × 2
And the result is:
52! = 6,082,818,640,342,675,608,722,271,304,417,978,642,816,780,000,000

The factorial of 8=
8!= 40320
So first we do
8 x 7. Obvi 56!! Now 56 x 6 = 336!

It turns out I'm not dumb. I understood the concept within 10 mins that the vid lasted, even though I couldn't get it within 45 minutes classes. I'm wasting so much time at school where I can't focus at all while I could simply study alone and know much more much faster.
Thank you so much for this! This is the first video I clicked on. My professor just threw this same factorial problem in the online lecture. I had no clue how he got 24 until now. :)
I learned a lot and it all made sense
