“hash” # key missing on Apple MacBookPro?

My first day on the Apple MacBook Pro and was playing around with ‘Numbers’ and wanted to insert the hash (#) symbol in the text.  For the life of me I couldn’t see the symbol anywhere on the keys of the keyboard.

After playing around for a while, I finally found it.  Alt + 3.  Simple when your find it, but frustrating trying to look for it.  I wonder how many other querks I’ll find in the next few weeks as I slowly transition from Windows to Mac.

Just to recap, Alt + 3 to enter the # symbol.
