In writing the integers from 10 through 99 inclusive, how many times is the digit 0 written?
+36 We know that the tens digit cannot be 0, so we can count the total number of integers between 10 and 99 with 0 as a unit's digit:
10
20
30
40
50
60
70
80
90
Hope this helped. Let me know if I did anything wrong!
