// Predict and explain first BEFORE you run any code...

// this function should square any number but instead we're going to get an error

// =============> write your prediction of the error here
//The error might be accuring because the parameter can't be a number and should be a variable 

// function square(3) {
//     return num * num;
// }

// =============> write the error message here
//the Error is a syntax error: Unexpected number 

// =============> explain this error message here
// we can put a number or any argument when we call the number not when we shape it 

// Finally, correct the code to fix the problem
function square(num) {
    return num * num;
 }

// =============> write your new code here
