In the first two In October 2021, two exceptional Cubans, as professionals and as human beings, died respectively, victims of the covid-19. Ricardo González Menéndez and Héctor Terry Molinet. Our column To Think pays this humble tribute, from Mathematics and knowledge.

I

Ricardo was born on 15011936, and died on 01102021

Héctor was born on 18031937 and died on 02102021

a. The sum of the four numerological digits of the previous dates, gives a number with a special meaning.

What is this number and what does it mean?

b. Using parentheses no more than twice, and no more than twice each of the four digits already indicated, construct the number of the sum of the years of life that each partner had at death. You can use only the four basic arithmetic operations.

c. The number of the day, in the year 2021, in which each colleague died has a classification that denotes the nature of such an unfortunate event. Why?

d. Discover a curiosity between the names of both companions and the days they died.
