# Basic D&D: Dice

Dice

This is a very important section. Be sure to read it carefully.Frank is serious: he defines "dice" and "die" and provides instructions for rolling the four-sided die, "the one that looks like a pyramid."

Examples include how to roll "percentile" from a ten-sided die.

Color the numbers

It is not uncommon to hear Grognards tell tale of crayons and "inking" their dice. In fact, D&D came with a wax crayon to do just that! I still do that with GameScience dice as they are not inked and tumbled—thus polishing and rounding the edges.

Dice Notation

d4, d6, d8, d10, d12, d20, d% (also seen currently as d100). "d" here short for "die" and read simply as "dee-four" meaning "4-sided die," not "die 4-sided". Collectively, these types of dice are created from platonic solids consisting of congruent, identical faces. All of them are called polyhedrons and have specific notations that can lead one down a deep rabbit hole.

Multiple dice of a type have a notation common of simple Algebra. 4d6 is read "roll a six-side die four times and total the result." Uncommon die, such as three-side die, or d3, can be rolled as well and might be noted as 1d6/2, or d6/2, rounding up.

Finally, there is 1d10+2, which results in values 3-13.

Dice notation has taken on a form in the three decades since D&D was introduced. Tools and calculators using notation like 4d6kh3, or "roll four d6 and keep the highest three dice." Some calculators capture specific groups and much more, almost in a form not unlike Regular Expressions in computer programming.

The end of this most important section simply ends with "YOU ARE READY FOR YOUR NEXT ADVENTURE!" Next Cadman will go shopping and prepare to venture into hills beyond town. And we get a closer look at Combat in BECMI from the player's side before doing so.

It is "simple Algebra." AC -2 is, literally, 19 - (-2) = 21 To Hit at 1st Level. Simple subtraction, yes, but the concept of subtracting a negative subtrahend from a minuend, q.v., the example, is not introduced until early concepts of Algebra are taught. Maybe sixth grade, but I'm old from a time when school was school and participatory and "No Zero" grading were verboten.

Comment:Roger at Wed, 4 Sep 10:13 PM“simple Algebra?” There seem to be many who complain about the simple subtraction of descending AC!
