- Abstract
The article "Problems and Solutions" in the magazine Gaceta de la Real Sociedad Matemática Española presents several mathematical problems and their solutions proposed by different people. The problems include topics such as cyclic quadrilaterals, integral calculus, divisible numbers, sequences of natural numbers, perpendicular and symmetrical triangles, numbers that satisfy equations, integrals, and probabilities. The solution to problem 441 proposed by Jules Verne is also included. The solutions to the problems use mathematical theorems and inequalities such as Fermat's theorem, Cauchy-Schwarz inequality, and Vandermonde's identity.
