They're not reversed, exactly. The "B" in "BC" stands for "before." The longer something happens before an event, the higher the number. It's like a countdown to takeoff: T minus 5 hours, T minus 2 hours, T minus 30 minutes, etc. When you count down to a certain time, the higher numbers are the earlier ones.
The BC dates count down to what we might call the year zero (but we don't, we call it the year 1). The event that everything is dated before or after in the calendar now used throughout the world is the birth of Christ. The BC dates count down to that event, measuring time before it, and the AD dates count up afterward.
If you've seen one of those kitchen timers that you can set for, say, an hour, you see it count down from 60 to 0 as time runs out. Some of those timers sound their beep and then start counting up to tell you how long ago zero was. BC and AD work just like that (except that people weren't actually counting down to Christ's birth beforehand, of course--other calendars were in use then).
BC, which is Before Christ, and BCE, which is Before Common Era, actually refer to the same thing. Years in BC/BCE work in reverse. So 12 BC/BCE came before 5 BC/BCE.
1900 years.
In terms of "BC" years, 750 BC is 50 years after 800 BC because BC years count down from the year before, instead of up like we currendly do in AD. For example, if this year were 2009 BC, next year would be 2008 BC.
One hundred years before 50 BC, it was the year 150 BC!

To find the answer you go both ways. Add 940+123 and get 1063. Then you minus 1 to get 1062. THERE WAS NO 0 YEAR!!! Remember BC is going in reverse and AD is going forward.
To find the answer you go both ways. Add 27+14 and get 44. Then you minus 1 to get 43. because there is no 0 year. Remember BC is going in reverse and AD is going forward.
