// Your task is to create a function that does four basic mathematical operations.

// The function should take three arguments - operation(string/char), value1(number), value2(number).
// The function should return result of numbers after applying the chosen operation.
// Examples

// basicOp('+', 4, 7)         // Output: 11
// basicOp('-', 15, 18)       // Output: -3
// basicOp('*', 5, 5)         // Output: 25
// basicOp('/', 49, 7)        // Output: 7


function basicOp(operation, value1, value2)
{
  switch(operation) {
  case '+':
    return value1 + value2;

  case '-':
    return value1 - value2;
  
  case '*':
    return value1 * value2;
      
  case '/':
    return value1 / value2;

  default: "Indefinido"
