Details about me

- Hi everyone! My name is Justin Stevens. I am currently a seventh grader living in Prospect, Kentucky. I am 13 years old currently, and was born April 30th/1998.

Math contests

Below will discuss all math contests I have participated in.

AMC

AMC 8

I have not taken an AMC 8 yet.

AMC 10

AMC 10B 2011

I got a 96 on the AMC 10B in 2011

AMC 12

I have not taking the AMC 12 yet.

Mathcounts

Mathcounts 2011

School

I got a 19 on sprint. I don't remember what I got on target.

Chapter

I got a 20 on sprint and a 12 on target. I got 25th place out of approximately 180 kids.

Artofproblemsolving

I joined artofproblemsolving in May, and enjoy posting solutions and moderating the Alcumus forum.

AoPS classes

Algebra 1

Over the summer of 2010, I took Algebra 1. I very much enjoyed this class. It included the quadratic formula ( $\frac{-b\pm\sqrt{b^2-4ac}}{2a}$ ), solving equations like: $2x+y=50$ $x-y=25$ Which would give us $x=\frac{75}{3}=25$ and $y=-2$ . It also taught me graphing and slopes ( $\frac{y_2-y_1}{x_2-x_1})$

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, $\pmod{}$ , and a lot of interesting number theory formulas (Ex: $gcd(x,y)=p_1^{min_{e_1,e_2}}*p_2^{min_{e_3,e_4}}*p_n^{min_{e_{2n-1}, e_{2n}}$ (Error compiling LaTeX. Unknown error_msg).

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, $\binom{N}{R}$ , Pascals triangle, Pascals Identity, and my username ( $(x+y)^n=\binom{n}{0}x^n+\binom{n}{1}x^{n-1}y+\binom{n}{2}x^{n-2}y^2\cdots \binom{n}{n-2}x^2y^{n-2}+\binom{n}{n-1}xy^{n-1}+\binom{n}{n}y^n)$

-==School==
-Throughout school, I have always found math to be easy for me.  A little bit about schooling.
-=== 4th grade===
-In 4th grade, I began learning basic Algebra, along with these sheets with approximately 50 math problems.  They ranged from division to multiplication to addition to subtraction.  I got a best score of 49 seconds on 50 math problems.  I had memorized 1-10's in addition subtraction, division, and multiplication.
-===5th grade===
-In 5th grade I still was in a mathematics class, however we did basic Algebra again.  It was still an easy year.
-===6th grade===
-My school has one AP class for 6th grade math.  It was Pre-Algebra.  It got extremely easy, to the point I would be putting "QED" on most problems for my homework.
-===7th grade===
-At the end of 6th grade, and in the summer going into 7th grade I took Introductory to Algebra online.  I loved it, and had a lot of fun.  In the fall, I took Introductory to Counting and Probability and Introductory to Number Theory.  I had a lot of fun taking these two classes with a lot of friends.
-Currently, I am taking Algebra 2.
