How To Play:

To play, drag the cards and operators (add, subtract, multiply, divide) to the chosen positions. Each card can only be used once, but math operators can be repeated.  Only whole numbers zero or greater can be calculated.   

Tapping on a card or operator places it in the next open location from left to right. Tapping on a card or operator in the equation removes that item.

The numbered cards are equal to their face value with "A" = 1, "J" = 11,  "Q" = 12 & "K" = 13.
