Lê Quốc Trần Anh ,"not greater" doesn't mean "smaller".It means \(\le\)

Hence,the answer is : 2017 - 0 + 1 = 2018 (numbers)

2019 số

We call the natural numbers: \(x\)

From the context, we have: \(x< 2017\)

The least possible number is: \(0\)

The largest possible number is: \(2016\)

So there are: \(\left(2016-0\right)+1=2017\left(numbers\right)\)

So there are \(2017\) numbers are not greater than 2017.
