ok, so timesFive is the function, it is called adding the parenthesis after it with an argument inside, so timesFive(5)
this mean that the function timesFive is called with a value of 5 for the parameter sas, that means that the line return sas * 5 would execute as return 5 * 5 (because sas takes the value of 5)
so, that, which evalue to 25 is the output of the function
so timesValue(5) is 25
and 25 is stored in the variable answer with =
