Abstract
Outreach talk How do multiplication tables look? Curiosities and secrets of algebra and geometry, given at Sierra Papacal primary school, Yucatán, on 20 March 2026, as part of the Divulgando-Mateamor programme (MateMayab / CIMAT–PCTY). Young audiences are invited to see multiplication tables as geometric objects—curves, symmetries and patterns linking elementary arithmetic with spatial intuition, with no formal prerequisites.

What this event is

Outreach mathematics talk How do multiplication tables look? Curiosities and secrets of algebra and geometry, delivered at Sierra Papacal primary school (Mérida area, Yucatán) on 20 March 2026, within the Divulgando-Mateamor programme with MateMayab (CIMAT-Mérida) and the CIMAT–PCTY ecosystem.

Talk outline

  • Motivation: multiplication tables are not only rote memorisation—they can be drawn and reveal unexpected shapes.
  • Core ideas: patterns, symmetry, a geometric reading of simple operations, and curves that appear when products are plotted in different representations (related to the earlier outreach talk Matemáticas con amor: las tablas de multiplicar en un reloj on the Spanish site).
  • Style: primary-school friendly language; emphasis on exploration, visual examples and participation.
