I think Khan's Academy is awesome. He received like $2 Million from Google to continue his work. I even use some of his videos for Trig help haha.
I think that site's an amazing tool. I understand this multiplication, obviously, but who knows what other hidden gems of math are out there for me to learn!
This is so great! Spreading education is always a positive act, even if it's as easy as fourth grade math. :)
Explain Euler's Identity!Please.
haha multiplication is my favorite part of math
Thanks for the share.
Sending this link to my little sister, doubt she will even do it though
Maths was always my worst subject at school!
Thanks for the help mate !
Hmm people who also haven't done any math in years can benefit from the links I think.
entertaining time killer
