First video I tried was way to long then I found this one and I instantly understood! Easy and short explanation. Got me through my hw and did it without references!
Thank you so much for making this much easier. Two questions that I have are, will that method of calculating the determinate hold for larger matrices and could I calculate the determinates of flat or tall matracies in the same way?
You’re welcome Hendrik. Taking determinants only works for square matrices so it will only work if the number of rows and columns are the same...not sure about 4x4, 5x5, etc...
Ok that makes sense, thank you very much. Would you consider doing a video dedicated to determinates in future, one where you look at the uses of it and the different ways to find it? I'm only starting matricies now and I think it will be a really useful video. but as I said I don't know much, that's just a newbie's opinion. Thanks Again.

+Pre- Eminence Some curriculums and some books are different. Oftentimes you will learn this technique when learning about matrices. If you know how to solve systems of equations by elimination or substitution or graphing those will all accomplish the same thing.
Best teacher alive🙏
You are the best tutor I have come across online
Dude you have just plucked me out of a advanced algebra mental downward spiral. You are a saint.
Glad my video helped you turn things around Zacha-Re!
Thank you for making this so easy to remember!
+Angela Belcastro your welcome!
thank you! your method is so much better than having to learn the rules
You’re welcome! Glad you liked my video Nahoy!
Professor Xavier Thanks!
I really like this explanation. Thank you!

Glad it helped!
Thank you for making this!! It actually makes sense when you do it
Blew my mind.
Thanks so much, my teacher could never explain it this well
Mario is the man!
You made this sound very easy thanks
Glad my Cramer’s rule Video helped you Elijah!
Tank you Mr you just save my day
Very short trick to solve matrices by crammer,s rule
Thx so much for making this so simple

Hello sir , I am from India ,like your teaching very much
Glad you like my videos Ayush!
❤thank you for wonderful job
You're welcome 😊
You can understand us in very easily method ...Thanks
Glad you liked the video YUSHI!
You saved me thanks alot!
The way he calculated the determinant of the 3 by 3 matrix... how does it work? Is there a proof for it?
YOU ARE SO HELPFUL THANK YOU SO MUCH
Glad my video helped you Serena!
board should be closer. perfect
You sir have saved my grade
Great! Thanks for letting me know! I’m glad my video and channel are helping you!
Yes! Thank you so much!
outstanding
Glad you liked the video Sai!
How do you do 3 variables but only 2 equations?
How are you sooo good at teaching?
Glad you like my teaching style!
How we use this short trick in exam?
Am not getting the 3 and 1😢
Nice
Wow well explained you saved the day👍
Do this in Excel
What level of mathematics is this? Great vid, btw.
+Pre- Eminence Generally students learn about Cramer's rule in Algebra 2 and/or PreCalculus.
I took both and didn't learn any of them. it wasn't part of our curriculum, I guess.

Wow
What he did in 5 mins. My prof took 2 hours.
Glad my video helped shorten the learning curve Bhumik!
