Syntax  
A+B A-B Arbitrary chains of addition and subtraction.
A*B A/B Arbitrary chains of multiplication and division.

(E) Parenthetic expressions
A<<B Counts the quantity of values in A that are lower than or equal to the value B. 10d6 << 3 counts the number of dice at 3 or below.
A>>B Counts the quantity of values in A that are greater than or equal to the value B. 10d6 >>4 counts the number of dice at 4 or above.
A<B A>=B Equality comparison on A and B. Must be the last operator ((1 < 2) * 5 is invalid, 1 < (2 * 5) is valid). Supported operators: < <= > >= =
X#A Evaluates the expression A X times. Use for stat generation: 6#4d6d1
