You can calculate one by one. But easy way for me is get the last digit for 1, 11, 21, 31, ...first, so there is ten 1 appearing. Then get the first digit from 10-19, there is ten 1 appearing. It is the same for 100-200. Next is get the hundredth for 100-199 which is appearing for one hundred time. So the total of no 1 appearing is 140
