Permutations

[@anounymousgamer2329]

this guy is a legend. I learn more in 10 minutes from him than I ever did with my teacher ❗❗

[@Iamtenialovely]

Cuz all they do is send us straight to him and teaches us nothing

[@hemangvasu3756]

Wow this has helped me so much! I am preparing for the TJ test and I didn't really know much about probability, combinations, and permutations. This was a descriptive video that I could actually understand. My teachers will skip few steps that we should know, but sometimes you get lost in the problems. You explained every step and I really appreciate you teaching me.

[@jdstall2264]

you are a God send...makes so much more sense the way you explain things..

[@ZaheerAhmed-qu5ho]

Thanks man I pass my class because of watching your videos you are method is very clear and easy to understand .

[@lavendano4921]

Excellent method of explaining it to middle school students. Thank you!

[@jalenemillard835]

[@tdunahoo2497]

[@rochellehoward3580]

How can you tell when order does or doesn’t matter?

[@matematicasbasicasdeconstr8992]

Good job.

[@greenbongos]

I really wish you would go a bit slower with the calculator part, I can’t see when you input the factorial button.

[@Mathispower4u]

Sorry about that. You can slow the speed of the video. It is one of the options if you click on thereare the bottom right.

[@greenbongos]

@@Mathispower4u Thank you, I was really frustrated when I wrote that and if it wasn't for your videos, I would be lost in space for ever. Seriously, thank you for what you do, these videos are done so well.

[@SINISTER5100]

at the 9:36 mark you divided by 8 instead of 8! so i think that's a mistake because in the following problem you do divide by 60!

[@bcechsmath8962]

3!4!5! does not equal 60! He is dividing by (2!2!2!) = (2*1*2*1*2*1) = 8. In the following problem, he divides by (3!4!5!) = (3*2*1*4*3*2*1*5*4*3*2*1) = 17280. While this number is large, it is much smaller than 60!.

[@ellaiyarasankalidass5699]

great, thanks.

[@Mia-fl9on]

how would you do this without a calculator?

[@CloudDinoGod]
