PROBLEM:

**Jen has to number the 396 pages in her biology notebook. How many digits will she have to write?**

I got the answer **1075 digits** by:

pages 1-9 = 9 digits

10-99 = 178 digits (99-10 = 89 #s. 89 x 2 digits = 178)

396-100 = 888 digits (396-100 = 296 #s x 3 digits = 888)

9

178

+ 888

_______

1075 digits on 396 pages

Again, if anyone can help go over this it would be a great help!

Thank you
