Children often ask, “Why?” This curiosity leads to questions like, “Why does 1+1 equal 2?” or “Why memorize multiplication tables?” Many stop questioning as they grow older. However, Dr. Eugenia Cheng, a mathematician, encourages us to continue asking, “What’s the point of this question?”

Imagine a situation where 1 + 1 equals 1. This occurs when mixing two paint colors, resulting in a single new color. Dr. Cheng explores such concepts in her book, Is Math Real? How Simple Questions Lead Us to Mathematics’ Deepest Truths. She demonstrates how these queries can reveal the beauty of mathematics.

Dr. Cheng’s book examines how we engage with math beyond the classroom. It challenges the binary true/false mindset taught from an early age. From instances where 1+1 does not equal two to infinity’s concept, Is Math Real? encourages us to rethink our connection to abstract math. It emphasizes that math thrives on curiosity and creativity rather than strict right or wrong answers.
