Singapore's Education System, with elite-students getting preferential treatment and ones who need more help left to fend for themselves. (See the movie I Not Stupid Too)

Yes to:

John Locke's Theory that humans are characterized by reason and tolerance (they are not born evil)

Ratings:

America: From Freedom to Fascism: ** - Interesting idea... not much support. So much for the 'revolution'

Simpsons: **** - maybe it's too intellectual for me... I just want a good laugh without the need to think.

Note to self:

Worksheet Question #21:

${\frac {2{\sqrt {7}}+{\sqrt {3}}}{3{\sqrt {7}}-{\sqrt {3}}}}\times {\frac {3{\sqrt {7}}+{\sqrt {3}}}{3{\sqrt {7}}+{\sqrt {3}}}}$

Taking the bottom part first:

$(3{\sqrt {7}}-{\sqrt {3}})(3{\sqrt {7}}+{\sqrt {3}})$

Expand it:

$63+{\sqrt {189}}-{\sqrt {189}}-3=60$

Now the top part:

$(2{\sqrt {7}}+{\sqrt {3}})(3{\sqrt {7}}+{\sqrt {3}})$

Expand it:

${\sqrt {1764}}+{\sqrt {84}}+{\sqrt {189}}+3$

Note:

${\sqrt {84}}+{\sqrt {189}}=2{\sqrt {21}}+3{\sqrt {21}}=5{\sqrt {21}}$

Simply:

$42+5{\sqrt {21}}+3=9+{\sqrt {21}}$

Putting the two parts together, we get: ${\frac {9+{\sqrt {21}}}{60}}$

Multiple Choice Answer: C

You gotta be kidding! The last step (where 5 disappears and 9 appears) makes no sense at all!
