Dear Math, you were wrong | Allegra Savegnago | TEDxEscola Concept Ribeirão Preto

Allegra Savegnago questions the everyday meaning of division: mathematics treats dividing as making a number smaller, while life can show that sharing knowledge and experiences makes them grow. She describes starting a project to teach public speaking and communication classes at another school, and how sharing her ideas and knowledge widened her own learning. The talk also introduces the "Protégé Effect," studied by scientist John Nestojko, which suggests that learning with the aim of teaching others leads to a deeper, more organized and critical understanding of material. The speaker invites viewers to rethink division as a way of multiplying generosity and love.

• Division in math versus division in everyday life
• A student-led project teaching public speaking and communication
• The Protégé Effect and learning by teaching others
• Sharing knowledge and generosity as a way to multiply

In this TEDx presentation, Allegra Savegnago reflects on how mathematics teaches that dividing means decreasing, while life shows that dividing can actually mean multiplying. The speaker shares her experience of creating a project to teach public speaking and communication classes at another school, overcoming initial hesitation and realizing that sharing her ideas, experiences, and knowledge expanded her own learning. She also introduces the "Protégé Effect," studied by scientist John Nestojko, to demonstrate that learning with the intention of teaching others enables a deeper, more organized, and critical understanding of the material. Allegra invites the audience to redefine the concept of division, reminding us that while dividing numbers reduces values, sharing potential, dreams, knowledge, and affection serves to multiply generosity and love.
