Amidst the global pandemic, they took the celebration to a virtual mode and organized a Google meet. There were around 100 participants including teachers, and about 30 students from the passing out batch. The event started with a warm welcome given by the anchors Vibhor, Prashant and Deepika from 2nd year.  Right after the introduction, there was quiz circulated among the seniors to break the ice. The air was then filled with love by Yukti’s(3rd year) melodious song. Moving forward, “Emoji Pictionary” was played; seniors were supposed to guess the names of the movie or dialogue through the emojis displayed on screen.

  • Amidst the pandemic, the 'Harish Chandra Mathematics Society' of Deen Dayal Upadhyaya College organised its annual fest 'MATHRIX'  from March 10 to March 12 in an online mode. The HCMS society of Mathematics Department organises its fest each year to give students a platform to showcase their mathematical understanding, reasoning capabilities and aptitude skills. It motivates them to come forward and learn new experiences to become acquainted with the competition in the real world. Of all the events conducted, 'Ganitya'- this year's mathematical quiz, had 245 registrations from various colleges. It had three rounds, two of which took place on 'Dare2Compete'. 97 participants appeared in the first round of the quiz that took place on March 10. Participants had to attempt 15 MCQs in 30 minutes. 31 participants managed to hustle through the first round. The second round, held on March 11, had 15 questions. The time limit was of 35 minutes. Out of those 15 questions, 10 were numerical answer type, while the remaining 5 were Multiple Select Questions. The most impressive and captivating part of the quiz was the Buzzer Round which took place on google Meet on March 12. 16 participants reached the last round; they had two minutes for each question. There were 15 questions in all. The exciting part about this round was the inclusion of the concept of negative marking. Two marks were awarded for an accurate answer, while each wrong answer was worth the deduction of one marks.  This round was not only about problem-solving. It was about speed, too. The person who answered first had the advantage. Those who performed well to reach the capstone were awarded cash prizes and certificates. Four students won the quiz, of which two were first rank holders.

Vision statement
“Live as if you were to die tomorrow. Learn as if you were to live forever”said by MahatmaGandhi is the motto of Department of Mathematics, DDU. Universities, they say are the ivory towers, and mathematicians are regarded as the epitome of those who inhabit them. Mathematics is a key player in numerous success stories of technical advantages and cost savings that accrue from clever modelling, analysis, and computation by mathematicians working with other professionals. The mathematician's logical, problem-solving approach is widely seen to provide a noticeable competitive edge. 
 
The Department of Mathematics is running efficaciously its major in mathematics since 1995. The department has at present seven permanent Associate Professors and one Assistant Professor, along with four additional qualified faculty members. The basic resolution of the department is to explore and give an insight in to the latest developments in mathematics to the future generation of students. 
 
The department believes in the holistic development of a student. In order to understand and to keep pace with the latest developments in the field of Mathematics which is a life-line of the present and future generation. As an initiative in this direction, the department has Harish Chandra Mathematics Society(HCMS) which organizes seminars, conferences and inter-college competitions annually. The society also organizes HCMS-lecture series by eminent mathematicians from time to time. Icing in the cake is the annual magazine Mathema  of HCMS. Department has a strong tradition of mathematical research..

REPORT- MATHRIX 15
 
The annual mathematics festival of Department of Mathematics, MATHRIX-15, held on 13th and 14th February 2015. There were total ten events in it and students of our college and other colleges participated in them. These events are held for the last five years. Mathematical Rangoli (Spectrum), Paper presentation are main attractions of this fest and different colleges participate in the festival. This time Shivajicollege, I.P. College for women, Department of African studies, Rajdhani college participated in different events.
 
Following events were included in the festival and most of them were mathematical:
 
  • PAPER PRESENTATION - Students present mathematical topics of their interest.
  • MATHEMATICAL TAMBOLA - It is similar to simple Tambola but the main difference is that instead of saying numbers, we will be speaking a logical solving type of a question where the participants will pretend the number and cut that number in the card provided to them. For example: if we want to say a number 2, then we can represent it as L.C.M. of [4,2] where the participant has to recognize it as 2 and cut that number in the card. The winner will be the one who will cut all the numbers first on his/her card.
  • MATHEMATICAL QUIZ - Purely mathematical event in which tricky questions from mathematics are asked to the participants.
  • SUDOKU - Sudoku consists of a 9×9 square grid containing 81 cells. The grid is subdivided into nine 3×3 blocks. Some of the 81 cells are filled in with numbers from the set {1,2,3,4,5,6,7,8,9}. These filled-in cells are called givens. The goal is to fill in the whole grid using the nine digits so that each row, each column, and each block contains each number exactly once.
  • SPECTRUM - The event is also known as mathematical rangoli. The students make rangoli patterns using mathematics. The judges ask each team questions about the pattern they make and test their knowledge about the mathematical concepts they have used.
  • SNAKES& LADDERS - This is a snakes and ladders math game. If the participant answers the question correctly then he/she get a chance to click and roll the dice each time. When the dice stops rolling, he/she move the number spaces that pops up on the dice, if the person is lucky, he/she will climb up a ladder but also watch out for the snakes. If the chip lands on a snakes mouth, it will be swallowed and sent back to start. 
  • REBUS PUZZLE - This event is about solving Pictogram Puzzles. In mathematical Rebus puzzle, we ask those pictorial puzzles which involve the participants to think and solve them mathematically as well. These Math Rebus Brain Puzzles serve an amazing brain activity for those who crave for mathematics everywhere.
  • CUT AND DRAPE - Mathematics involved here is the correct measurement before cutting the papers.
  • RIDDLES - For students’ entertainment.
  • TREASURE HUNT - For students’ entertainment.
