Dueling Digits

From the manual To control your scarab number collection machine you must use the paddles or joystick. Your object is to shoot the floating numbers and mathematical operands and place them down below in a balanced mathematical expression such as 234 + 14 = 248. The computer is not particular about where you leave blank spaces, so it would also accept 2 34+1 4=2 48. No operands may be on the right side of the "=" sign and the result may not be equal to 0. The scarabs to the side indicate how many machines you have left. You may shoot and be shot by the other player which results in an award of 10 points to the shooting player and the loss of a piece to the victim.
