===Algebra 1===
 
Over the summer of 2010, I took Algebra 1.  I very much enjoyed this class.  It included the quadratic formula (<math>\frac{-b\pm\sqrt{b^2-4ac}}{2a}</math>), solving equations like:
 
<math>2x+y=50</math>
 
<math>x-y=25</math>
 
Which would give us <math>x=\frac{75}{3}=25</math> and <math>y=-2</math>.  It also taught me graphing and slopes (<math>\frac{y_2-y_1}{x_2-x_1})</math>
 
 
===Introductory to Number Theory===
 
Over the fall of 2010 I took Introductory to Number Theory and Introductory to Counting and Probability.  In number theory, I learned base numbers, <math>\pmod{}</math>, and a lot of interesting number theory formulas (Ex: <math>gcd(x,y)=p_1^{min_{e_1,e_2}}*p_2^{min_{e_3,e_4}}*p_n^{min_{e_{2n-1}, e_{2n}}</math>.
 
 
===Introductory to Counting and Probability===
 
Over the fall of 2010 I took Introductory to Number Theory and Introductory to Counting and Probability.  I learned Permutations, <math>\binom{N}{R}</math>, Pascals triangle, Pascals Identity, and my username (<math>(x+y)^n=\binom{n}{0}x^n+\binom{n}{1}x^{n-1}y+\binom{n}{2}x^{n-2}y^2\cdots \binom{n}{n-2}x^2y^{n-2}+\binom{n}{n-1}xy^{n-1}+\binom{n}{n}y^n)</math>
