The Teen Titans team never gets bored; every now and then another villain appears who wants to do harm to anyone. This time the villain is called Calculator and he needed energy to destroy the city. For this purpose, he kidnapped Cyborg to take his batteries. Reiveg, Robin, Beast Boy and Starfire are ready to fight, but Calculator is ready to fight only mathematical battles, which came as a complete surprise to his friends. They are powerless in this and only you can help the heroes. Each hero will operate with his own sign. For Robin, the plus will become important and you will help him balance the bridges so that he can drive across them. Beast Boy must multiply fireballs, Raven must use her calculator to figure out the correct answers to subtraction examples, and Starfire must climb to the top of a skyscraper thanks to your answers to division examples in Battle with Numbers.
