How smart are you: Then solve these tough Mathematical numbers.

1. In a 10 by 10 grid of dots, what is the maximum number of lines that can be drawn connecting two dots on the grid so that no two lines are parallel?
2. If r_1, r_2, and r_3 are the solutions to the equation x^3 – 5x^2 + 6x – 1 = 0, then what is the value of r_1^2 + r_2^2 + r_3^2?
3. The expression \circ \ 1\ \circ \ 2 \ \circ 3 \ \circ \dots \circ \ 2012 is written on a blackboard. Catherine places a + sign or a – sign into each blank. She then evaluates the expression, and finds the remainder when it is divided by 2012. How many possible values are there for this remainder?
4. Parallel lines \ell_1 and \ell_2 are drawn in a plane. Points A_1, A_2, \dots, A_n are chosen on \ell_1, and points B_1, B_2, \dots, B_{n+1} are chosen on \ell_2. All segments A_iB_j are drawn, such that 1 \le i \le n and 1 \le j \le n+1. Let the number of total intersections between these segments (not including endpoints) be denoted by Q. Given that no three segments are concurrent, besides at endpoints, prove that Q is divisible by 3.
5. In convex hexagon ABCDEF, \angle A \cong \angle B, \angle C \cong \angle D, and \angle E \cong \angle F. Prove that the perpendicular bisectors of \overline{AB}, \overline{CD}, and \overline{EF} pass through a common point.
6. The positive numbers a, b, c satisfy 4abc(a+b+c) = (a+b)^2(a+c)^2. Prove that a(a+b+c)=bc.
7. For how many positive integers n \le 500 is n! divisible by 2^{n-2}?
8. A convex 2012-gon A_1A_2A_3 \dots A_{2012} has the property that for every integer 1 \le i \le 1006, \overline{A_iA_{i+1006}} partitions the polygon into two congruent regions. Show that for every pair of integers 1 \le j < k \le 1006, quadrilateral A_jA_kA_{j+1006}A_{k+1006} is a parallelogram.

The youngest iOS app developer in Europe.

In 2012, 12-year-old Jordan Casey from Waterford, Ireland, became  the youngest iOS app developer in Europe and one of the youngest in the world, when his first game, Alien Ball Vs Humans, went on sale on the Apple App Store. The game, inspired by Space Invaders, went to the top of the Apple iTunes store in Ireland.

His passion for programming started when Jordan was 9-years-old.  He was playing a Flash multiplayer game, called Club Penguin, and saw that other kids were developing websites and blogs about it. After creating his own blog assessing other people’s games, he decided to try developing his own games, so he learned 3 languages: HTML, ActionScript 2.0 and CSS and created his own website, Casey Games. By the age of ten, his website was receiving over 50,000 hits.
When describing Alien Ball vs. Humans, the young app developer emphasizes: “It is kind of the opposite of Space Invaders, because in space invaders you are the human destroying the aliens but in Alien Ball vs Humans, you are the alien killing the humans.”
He subsequently created Alien Ball vs Humans 2 and a puzzle-adventure game called Greenboy Touch. In an interview, he revealed:  “The first two games I developed cost 89 cent each to download. I am using a premium payment system on my Greenboy Touch game. You get the first part of the game free and you pay for the rest.” After initially offering them for free, in order to build up momentum, he started changing for them after a few weeks.
During the 2012 Cannes Lions Festival for Creativity in Communications, where he appeared as a guest panelist, he met a representative of Fabrica Brasil, a Brazilian advertising company, who asked him to develop an Android game, called Save the Day, in honor of International Children’s Day in Brazil. The game was played more than 15,000 times on Fabrica Brasil’s website.
Jordan has also developed one of the first Irish virtual worlds, Food World, a giant kitchen where players can create their avatar and explore the landscape and engage with friends. He developed this game with his first staff member, Aidan Blackett, a graphic designer.
In 2012, Jordan launched his computer gaming creation company, called Casey, which has produced the four previously mentioned games, which have gotten over 1,500 downloads. Due to his young age, he could not become legally became its director, so he made his parents heads of his company.
Jordan revealed that one of his greater challenges is making sure that the application enters the Apple app store, since, if the company finds the smallest problem with the game, they simply reject it.
In recognition of his games and company, Jordan has won several awards. Most recently, he received the Best Innovation Award in the Junior Category at the Student Entreprise Awards in Croke Park.  He also given speeches at TedxYouth New Delhi, The Smartphone and Tablet Games Summit and TiE conference in California, where he presented to 4,000 delegates “Things I learned the hard way as a young CEO.”
Jordan is also engaged in charity work, since 10 percent of his Greenboy game profits are donated to a cancer respite center in Waterford.
The young programmer is currently developing a new game, My Little World, about a tiny creature called JC, who lives in a garden and wants to see the real world. He hopes to release this game via iPhone, Android, Windows 8 and Mac platforms in October 2013. He hopes that programming will be soon taught in schools, because he believes “you can imagine something and do anything with programming. You can make games, you can make websites, you can make clocks or watches…”
