Proposal: Operands
Create a rule titled "Operands" with this text:
Operand is a player switch, tracked by the Numerator, with values
Sum (default), Difference, Product, and Quotient.
Once per month, a player CAN flip eir Operand by announcement.
Amend Rule 2714 (Spending Number Cards) by replacing the paragraph
starting "For any two decimal digits X and Y" with this text:
For any two decimal digits X and Y (which may be the same), a
player CAN pay 2 spendies, a number card of type X, and a number
card of type Y to grant emself a number card whose type is equal
(modulo 10) to:
* X+Y, if eir Operand is Sum
* X-Y or Y-X, if eir Operand is Difference
* X*Y, if eir Operand is Product
* A/B, if eir Operand is Quotient, for some numbers A and B
such that A = X (modulo 10) and B = Y (modulo 10)
