 // this function should square any number but instead we're going to get an error
 
 // =============> write your prediction of the error here
+// I think this is an obvious one because when defining a function you cant give a direct input like 3,
+//  instead you have to give a variable name as a parameter and then use that variable name in the function
+//  body to perform the calculation. So I predict that there will be a syntax error because of the way 
+// the function is defined with a direct input of 3 instead of a variable name.
