Children often ask ‘Why?’ when learning math. ‘Why does 1+1=2?’ or ‘Why memorize times tables?’ Many stop questioning, but mathematician Dr. Eugenia Cheng encourages us to keep asking. Her book, Is Math Real? How Simple Questions Lead Us to Mathematics’ Deepest Truths, pushes us to explore these inquiries further.
Dr. Cheng challenges conventional math thinking, suggesting alternate scenarios where 1+1 could equal 1, like mixing two paint colors to create one new color. Her book examines the application of math outside traditional classrooms, questioning the binary of true and false that we learn early on. It uses examples like 1+1 not equaling two and the concept of infinity to challenge mathematical rigidity.
She emphasizes that math thrives on curiosity and creativity rather than seeking only right or wrong answers.
