I'm a math teacher in California. I saw your TED talk and then looked you up on KZread. Thank you for bringing so much energy to your math class. I enjoyed watching this video.

Yeah I need the rest!!

These videos are such a key demonstration of how an engaging and enthusiastic teacher can absolutely make a class. I'm in my 30's, did all of this maths many years ago, but still enjoy these videos.

God damn it feels like I'm back in math class again, I love these videos. Ever since I dropped out of school I've been really missing learning like this and boy is this just the perfect thing me. Love it! keep it up!

FIRST. I LOVE YOUR STUFF EDDIE

Square root of a number produces two different numbers of equal magnitude and opposite signs which when multiplied by itself gives the number of which square root was taken. You are awesome and lots of love from India😇👍👌🙋‍♂️

The square root of 4 for example cant be -2 it is only 2 because the square root symbol without a negative always asks for a positive number only while if you are SOLVING for the square root it can be negative OR positive

Guru g . A very good morning from India. U teach awesome...

Hurry up and post part 3! I finished the question but want to know if I am correct! I got 4 solutions, but am not sure if any of them are extraneous?

Another day where I learned so nice things. Love it

Nice 😊

Can you make video on ratio and proportion, logrithm, time and distance please sir love from India ❤️

Please do a video on cube root

Interesting issue with cube roots. Try this experiement. With Google Calculator, evaluate: (-8)^(1/3) and (-8)^0.3333 For the first term, as expected, you get -2. For the second term, you might expect you'd get -2 as well. But unless you are using a calculator that recognizes the exponent as an exact fraction, you end up with a complex number that is seemingly nowhere near -2. It turns out, that the principal root of a cube root of a negative number, is a negative number itself. But if you are just slightly off from the exponent being exactly 1/3, then the convention for principal complex roots throws the entire thing off by 120 degrees, to the root in the first quadrant.

a=1 and b=square root of 3

Or a=-1 and b=-sqrt(3) you can factor out a negative and if you square it it's positive again.

@@SeeTv. No, if you were to do that, 2ab will become -2√3

Is that video recorded in a Chinese classroom?
