Need help understanding random class in java

Question

So I am currently trying to get hold off the random class and how its range works.
Lets say that i have "Random rand = new Random();

and i want to figure out rand.nextInt(10) * 4;
I get how to work with its range when using addition and subtraction (+, -)
but I cant work around the multiplication and division.
Can someone please explain it.

Answer 1

rand.nextInt(10) returns a random integer from 0 to 9... now you are multiplying that number by 4.
min number is 0*4=0
max number is 9*4= 36
So you will get a number in range [0,36]
All possible outputs: 0,4,8,16,20,24,28,32,36
