Formula:
The Random Dice Roller takes your desired Number of Dice (N) and Number of Sides (S) per die. For each of the N dice, a random integer between 1 and S (inclusive) is generated. These individual results are summed up, and an optional Modifier (M) is added to produce the Total Roll (T).
T = (Roll1 + Roll2 + ... + RollN) + M
