If that BB is english:

Stand in front of the driver side.... imagine how the BB axle moves when you are pedaling, the bearings move in the opposite direction (believe me). The BB cup tights in the same direction than the bearings move. Then obviously lose at the opposite direction... you put your tool and turn it clock wise to lose... or from the back of the bike to the front of the bike.

In italian BB... stand in front of the driver side cup, imagine how the BB moves when you are pedaling, bearings move in the opposite direction. The italian BB lose in the same direction than the ball bearings... that means clock counter wise. To lose the cup you put the tool and turn it from the front of the bike to the back of the bike.

Hope this helps better.
