Are you up to this addition and subtraction challenge? Welcome to the first annual all-pretzel arm wrestling tournament. Although you can’t hope to match the pure strength of the world’s best arm wrestling pretzels, you have one advantage – the strength of your pretzel-flexible arms is governed by your quick skills in addition and subtraction. Subdue your worthy opponents with your error-free calculations. Be careful though – errors you can afford to make in the first few rounds will lead to your demise in the last few rounds. Be quick —- and accurate. The calculations get harder as you move on, but you’ll have to make less of them in the later rounds.
