-// Line 3; when we the right side first count in the right side is considered as 0 so 0+1 will be 1.

-// Answer
-
-// 1. 
-// The num in this scenario represent any integer between 1 and 100
-
-// 2.
-// Math.floor: rounds the number down to the nearest whole number which means it ignores the number to the right of the point. eg. 4.7=4
-// Math.random is a js code that returns any random number that is greater than or equal to 0 and less than 1
-//* is multiplication
-// maximum is the maximum given number, in this case 100
-//- is a subtraction
-// minimum is the minimum given number, in this case 1
-//(maximum - minimum +1) this is subtracting the minimum number from the maximum and add 1, in this case (100-1+1)=100
