| − | ===MathCounts===
| |
| − | In 2011, as a 7th grader, I qualified for the State Countdown Round. In 2012, as an 8th grader, I qualified for National MathCounts. Hopefully, this page will be updated when I know the results of the National competition.

| − | ===AMCs===
| |
| − | 2012: 117 on AMC 10A, 127.5 on AMC 10B, 8 on AIME, 207.5 index for USAJMO. The cutoff was a 204.5, so I qualified for the USAJMO. Hopefully, this page will be updated when I know the results of the USAJMO.

| |
| − | My username is from the [[Quadratic formula | quadratic formula]], which states that the roots of the equation <math>ax^2+bx+c=0</math> are

| − | <cmath>x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}</cmath>

| |
| − | <cmath>\sqrt{a+bi}=\sqrt{\frac{a+\sqrt{a^2+b^2}}{2}}+i\sqrt{\frac{-a+\sqrt{a^2+b^2}}{2}}</cmath>
| |
| − | I derived that equation myself, and I am quite proud of it. I have a similar one for the fourth roots of <math>a+bi</math> which can be derived from inputting that equation into itself. I have also found various roots of unity in their radical forms during my spare time.

| − | ==Spirographs==
| |
| − | I have created a great number of spirographs, each interesting and unique. More can be found on my [http://www.artofproblemsolving.com/Forum/blog.php?u=93546& AoPS blog] (but you might have to look through a few pages of other stuff, too). To view the entire collection, please visit [http://www.negativebplusorminus.blogspot.com negativebplusorminus.blogspot.com], but again, you might have to scroll down a bit. Here are some samples:
