TABLES CAN BE REVERSED

The table of 1089 is VERY easy to remember.
1089*1=1089 reverse the digits 9801=1089*9
1089*2=2178 ............................... 8712=1089*8
1089*3=3267 ................................ 7623=1089*7
1089*4=4356 ................................. 6534=1089*6
.....................1089*5=5445 ....................


And the same goes for the table of 9
9*1=09..........90=9*10
9*2=18...........81=9*9
9*3=27 ...........72=9*8
9*4=36............63=9*7
9*5=45............54=9*6

The details are as follows...
"....
1. The contest will comprise of three rounds. The first round (round A) will be the short project presentation round, the second round (round B) will be quiz round and the third round (round C) will be a problem solving round.

2. The contest is open to students of class XI and XII. Each school should send a team of four participants of whom at least one must be from class XI. Two students will present their project in round A while the other two (the quizzers) will participate in round B. The quizzers must include one student from class XI and one from class XII. All participants are allowed to participate in Round C. Every team must be accompanied by a teacher.

3. Rules for Round A.
This is the Short Project Presentation Round. Each team must work on a project, which satisfies one of the following:
(i) The project must be based on some mathematical theory or it must highlight some mathematical concept.
(ii) The project must highlight some application of mathematics to a real life problem.
(iii) The project must be innovative in nature. Effort must be made by each team to make some original contribution to the problem at hand.
(iv) Projects must not reproduce text book material.

Each project must be supported by

(i) A project report comprising of not more than 8 to 10 A4 sheets typed in double space. No hand written projects will be entertained. Each project report must include a brief abstract (not more than 150 words), the aim or objective of the project, the mathematical theory, and findings and conclusions. Four copies of the report, duly signed by the head of the institution, must reach Delhi Public School R K Puram latest by 5th November 2005.

(ii) A computer presentation or a physical model. Special points will be given to teams who present their projects using both computer presentation and a physical model. Computer presentations can be made in MS PowerPoint or Flash. All teams must bring their computer presentations on CD’s only. No school will be allowed to bring their own CPU. If any other equipment is required for presentation, it must be brought by the participating team. Each team will be given 8 minutes for presenting their project.

(i) Originality of idea and innovativeness.
(ii) Practical relevance.
(iii) Presentation during the contest.

4. Rules for Round B.
This is the Mathematics Quiz Round. Questions posed in this round will be based on the following:
a. History of Mathematics.
b. Applications of Mathematics.
c. Mathematics concepts (from class XI and XII level)

5. Rules for Round C.
This is an on-the-spot problem-solving round where problems will be posed to the teams and they will be required to present the solution within a certain time.

The contest will be held on Tuesday, 22nd November 2005. Registration will be from 8:30 to 9:30 am. The competition will begin sharp at 9:30 am.

Cyclic Number?!!!

142857 is a cyclic number...

Multiply the number by any digit in 1 to 6.
The result will be a number having same digits as 142857 in the same order just rotated...
142857 * 1 = 142857
142857 * 2 = 285714
142857 * 3 = 428571
142857 * 4 = 571428
142857 * 5 = 714285
142857 * 6 = 857142
