The Game Of Rapid Calculation Everyone plays simultaneously to try to add, subtract, multiply or divide the right combination of cards in their hand to equal the Arithmanix number. The excitement builds as you race to be the first player to crack the calculation & then turn the timer to put pressure on your opponents to make their calculation before time runs out. Pile up the points by equalling the Arithmanix number, or minimise your losses by getting as close to it as you can. Keep it simple to score quick wins or go for bonus points with a more complex calculation, but be careful not to get caught out by the dreaded order of operations! Will you be the master of multiplication or be defeated by division? Every round throws up new number combinations & a new calculation to crack, in this clever game that you will want to play again & again.
