IOQM 2021 - Problem 1 Let $ABCD$ be a trapezium in which $AB \parallel CD$ and $AB=3CD$. Let $E$ be the midpoint of the diagonal $BD$. If $[ABCD]= n \times [CDE] $, what is the value of $n$ ? (Here $[\Gamma]$ denotes the area of the geometrical figure $\Gamma$).Answer: 8 Solution: IOQM 2021 - Problem […]
“The Pigeonhole principle” ~ Students who have never heard may think that it is a joke. The pigeonhole principle is one of the simplest but most useful ideas in mathematics. Let’s learn the Pigeonhole Principle with some applications. Pigeonhole Principle Definition: In Discrete Mathematics, the pigeonhole principle states that if we must put $N + […]

(২১-শে ফেব্রুয়ারীর প্রতি) ‘মাত্রা’ অথবা ডাইমেনশন কাকে বলে? একটু তলিয়ে ভাবতে গেলে কিন্তু সব গোলমাল হয়ে যায়। এই এক টুকরো লেখায়, আমরা ডাইমেনশন নিয়ে একটু ভাবা প্র্যাকটিস করব। একটা বিন্দু-র dimension কি? একটা সরলরেখারই বা dimension কি? একটা কাগজের টুকরোর dimension কি হবে? চট করে ভাবলে মনে হয় যে কিন্তু কেন এরকম মনে হচ্ছে? তুমি […]
In the world of fake olympiads and thousands of contests, it is important to select the right ones and focus on them. Children take hundreds of tests these days under peer pressure. No good comes out this rat race. We urge kids to learn deep mathematical science and prepare for 1 or 2 real contests […]
