+// Math.floor () and Math.random () are methods.
+// The value inside Math.floor() is its argument. The return value of this argument is expression within the yellow parenthesis.
+// The whole expression of variable "num" is that a float generated by method Math.random() is multiplied by return value of the range specified by value between declared variable by key word constant.
