 ## 💡 Pista:
 
 + Si no sabes cómo empezar la solución a esta asignación, por favor, revisa la teoría en esta lección:
 https://snakify.org/lessons/integer_float_numbers/
 
 + También puedes intentar paso a paso con trozos de la teoría:

+https://snakify.org/lessons/integer_float_numbers/steps/1/
+
++ Ten en cuenta que para concatenar dos números puedes transformar su valor en un string con str(num).
+
++ El valor a retornar debe ser un número entero.

 ## 💡 Hint:
 
 + If you don't know how to start solving this assignment, please, review a theory for this lesson:
 https://snakify.org/lessons/integer_float_numbers/
 
 + You may also try step-by-step theory chunks:

+https://snakify.org/lessons/integer_float_numbers/steps/1/
+
++ Note that you need to concatenate two numbers, so in order not to add those values you may have to convert them as a string (str)
+
++ The function must return a number
