The rules abbreviate dice rools with phrases such as ?4d6+2? which means ?four six-sided dice plus 2? (generating a number between 6 and 26). The first number tells you how many dice to roll(all of which are added together), the number after the ?d? tells you what type of dice to use, and any number after that indicates a quanitity that is added to or subtracted from the result.
Some examples;
3d6: Three six-sided dice, generating a number from 3 to 18. This is the amount of damage that a blaster pistol deals.
2d8: Two eaght-sided dice, generating a number from 2 to 16. This is the amount of damage that lightsabeer deals in the hands of a 1st-level jedi.
D%: The ?%? (percentile dice) is a special case. You generate a number between 1 and 100 by rolling two different-colored ten-sided dice. One color ten-sided dice. One color (designated before you roll) is the tens digit. The other is the ones digit. A roll of 8 and 5, for example, gives you a result of 85. A O and 3 equals 3. Rolling O and O represents 100.
