4 operaciones basicas en programacion modular

int sumar(int a, int b){
  return a+b;
}
int restar(int a, int b){
  return a-b;
}
int multiplicar(int a, int b){
  return a*b;
}
int dividir(int a, int b){
  return a/b;
}

int main(){
  int number_a = 5;
  int number_b = 2;
  int suma = sumar(number_a, number_b);
  int resta = restar(number_a, number_b);
  int multiplicacion = multiplicar(number_a, number_b);
  int division = dividir(number_a, number_b);
  
  printf("suma: %d", suma);
  printf("resta: %d", resta);
  printf("multiplicacion: %d", multiplicacion);
  printf("division: %d", division);
  return 0;
