This would have made me like learning in high school if my math teacher was this cool. Even though you can see him behind the desk it's still wicked!

The demonstration for 1=2 is more a trick, a "faulty" demonstration. It goes like this:
Let a=b .
We multiply by a and we have a^2=a*b .
Then we add a^2 and we have a^2+a^2=a^2+a*b .
Now we subtract 2*a*b and we have 2*a^2-2*a*b=a^2+a*b-2*a*b .
Which can be written as 2*(a^2-a*b)=a^2-a*b .
Now we divide by (a^2-a*b) and we have 2=1 .

The problem is that a^2-a*b is 0 in this example, so 1*0=2*0.
Note that a^2 means a squared.

wow

Probably took him endless hours to sync up and make it look so perfect.

Imagine if he didn't have a laughing class, that would have been sad.

wish all teachers like that, not like those union teachers that only care about their pay check and job security and not about teaching.

Excellent. I'd of learnt so much more at school if my teachers would have been as open and fun as this guy.
