Only one term may be equated with another. Two of the same card may not be used in a single equation. A single card may not be shared by two equations. See the Sample Equation for further explanation. The point value assigned to each card is simply the number of units required to form the quantity.
Players receive points only for the cards that are involved with a balanced equation.
This relationship is built by breaking the quantities down to their base units and factoring out the appropriate units. For the above equation, the cards should be placed on the table as shown here. By separating the cards as shown above, the equals sign is implied. The upper left corner of the card has the same MKSA symbol, represented in terms of the base units of distance, mass, time, angle, and electric current. This allows the players to hold their cards in a fan arrangement while still being able to see the various fundamental units for each of the cards.
