Can you also try explaining the meaning of each sub-expression?
Math.random()
Math.random() * (maximum - minimum + 1)
Math.floor(Math.random() * (maximum - minimum + 1))
Math.floor(Math.random() * (maximum - minimum + 1)) + minimum

Math.random(): Gives a random number between 0 and 1.
Math.random() * (maximum - minimum + 1): Stretches the random number so it can cover all the numbers in the range, stretches 0 to 1 into 0 to 100.
Math.floor(Math.random() * (maximum - minimum + 1)): Removes the decimal part so we get a whole number.
Math.floor(Math.random() * (maximum - minimum + 1)) + minimum: Adding the minimum moves all the numbers up, so the lowest equals the minimum I chose.

Phrases like "a number between X and Y" are not precise enough in a program specification, because they do not clearly state whether the endpoints X and Y are included.
You can consider using the concise and precise interval notation to describe a range of values.
[,]=> inclusion(,)=> exclusion
If -5 < x <= 50, we can say x is a number in the interval (-5, 50].
Can you lookup the return value of Math.random() and describe its return value using this notation?
