How many 3-digit numbers have the hundreds digit equal to seven and the units digits equal to eight?
The form of a three-digit number is "XYZ"
This question is asking you to find how many of these have the form "7Y8"
Y can take any one of the values {0,1,2,3,4,5,6,7,8,9}, so  numbers have this form. I hope this makes sense to you.
