Mathematical Expeditions 2

This is part of an expedition throught the history of word problems. It is adapted from the book Mathematical Expeditions by Frank J. Swetz.

This is a word problem from Renaissance Europe related to shares. Do you dare solving it?

A man had four creditors. To the first he owed 624 ducats; to the second, 546; to the third 492; and to the fourth, 368. It happened that the man defaulted and escaped, and the creditors found that his goods amounted to 830 ducats in all. What will be the share of it?

Explain the procces and the answer using comments. Write your name and course.

Interpolation

Did you know?

You can use polinomials to interpolate unknown values. Try to discover a little more:

• What is interpolation used for?
• Which is the simplest interpolation that can be made?
• Here you have an image of the first time that the word "interpolation" was used in a mathematical sense. Who used this word for the first time?

Time Goal: November 20th.

Constitución de 1812

Como sabréis hoy es el 200 aniversario de la aprobación de la primera constitución española, la constitución de las Cortes de Cádiz. ¿Sabias que en uno de sus artículos habla de las matemáticas?
