 # OpenBootCampPython
 Repository to store Python boot camp.
+
+Ejercicio 7.A: En este ejercicio tendréis que crear un módulo que contenga las operaciones básicas de una calculadora: sumar, restar, multiplicar y     dividir.
+
+Este módulo lo importaréis a un archivo python y llamaréis a las funciones creadas. Los resultados tenéis que mostrarlos por consola.
