  Srinivasa Ramanujan – The Man Who Knew Infinity Introduction Srinivasa Ramanujan was one of the greatest mathematicians the world has ever known. He was not just a mathematician, but a symbol of pure genius, dedication, and faith. Born in poverty, without formal higher education in mathematics, Ramanujan made discoveries that still influence modern mathematics today. His life story is both inspiring and heartbreaking, showing how talent can rise even in the hardest conditions. Early Life and Family Background Srinivasa Ramanujan was born on 22 December 1887 in Erode, a small town in the Madras Presidency (now Tamil Nadu, India). His father, Kuppuswamy Srinivasa Iyengar, worked as a clerk in a cloth merchant’s shop, earning a very modest income. His mother, Komalatammal, was a housewife and a devout religious woman who sang devotional songs at a local temple. Ramanujan grew up in Kumbakonam, where the family faced financial difficulties throughout his childhood. From a very young ...

 Here’s a Blogger-ready post with title, content, and clear answer 👇 Title: How to Find the Value of ab When a+b and a²+b² Are Given Content is In algebra, many problems can be solved easily by using identities instead of lengthy calculations. Let us see one such example. Given: a^2 + b^2 = 100 and a+b=12 We are asked to find the value of ab. Step 1: Use the identity    (a+b)² = a² + b² + 2ab => (a+b)²  - 2ab = a² + b² Step 2: Substitute the given values    100 = (12)² -2ab => 100 = 144 - 2ab Step 3: Solve for ab     2ab = 144 - 100 => 2ab = 44 => ab = 22 Final Answer:  ab = 22 Conclusion: Using algebraic identities helps us solve problems quickly and accurately. This method is very useful in exams and competitive tests.
