I have a collection of lessons divided by levels Each level has 10 chapters.
level 1 = chapter 1 to 10
level 2 = chapter 11 to 20
level 3 = chapter 21 to 30
and so on..
So my question is, what is the math formula to get the level by only knowing the chapter.
Let's say I want to know the level of chapter 12.
it should be:
level = function(12 ...)
Thank You
