Now suppose that numeral prefixes were allowed. How would you interpret this?
101V=100
as
10 1V = 100
or as
101 V = 100
or as
1 01V = 100
So, this was made illegal.

Ignore parent padding
...ngth of the parent div. This is because the padding is NOT included in the 100px width, this means that it's actually 120px wide, and your <hr> will be 20px from the end of your div. See this jsFiddle for what I mean: jsfiddle.net/YVrWy/1

What is a plain English explanation of “Big O” notation?
...we have to add together 6 digits (and possibly carry a 7th). If we add two 100 digit numbers together we have to do 100 additions. If we add two 10,000 digit numbers we have to do 10,000 additions.
See the pattern? The complexity (being the number of operations) is directly proportional to the num...
