Remember in high school, doing math you thought you'd never use? Well Gearing Ratios is one of those things!
In general:
A smaller front (countershaft) sprocket or larger rear sprocket will make your bike accellerate faster, but have a lower top speed. It will also make the chain slightly looser, and you will probably need to move the rear wheel back slightly to compensate. This creates a lower gearing ratio
A larger front sprocket or smaller rear sprocket will make your top speed faster, but your accelleration will be slower. You may need to move the rear wheel forward slightly. This creates a higher gearing ratio
As a general rule, changing one tooth on the front sprocket is roughly equal to changing the rear by four teeth!
Now for the ratios
