The seventh book in the harry potter series has 759 pages. How many 2s were used when typing the page numbers?
each ten has one two. that is 76.
each hundred has one twenty, so that is 10 for each hundred (20,21, ..) 80
each thousand has a 200, 201, so that is another 100
I count 100+80+76

every 100 has 20 2's except in the 200's there are 120 2's
umm i think u added wrong cause i got 255 and u got 256
To find out how many 2s were used when typing the page numbers in the seventh book of the Harry Potter series, we will need to analyze each page number individually and count the number of occurrences of the digit 2.
Here's how you can do it:
1. Start by examining each page number from 1 to 759.
2. For each page number, check if the digit 2 is present.
3. If the digit 2 is present in a particular page number, count it as one occurrence.
4. Repeat this process for all page numbers in the range of 1 to 759.
5. Finally, sum up all the occurrences of the digit 2 to get the total count.
This method will ensure that you accurately count the number of times the digit 2 appears in the page numbers of the seventh Harry Potter book.
