 The function `math` should multiply the second and third arguments, then add the first argument to the outcome of the multiplication and return the value obtained.
 
 After that, inside the parentheses of `console.log()`, call the `math()` function with the number 53 as first argument, the number 61 as second and the number 67 as third argument.
