Trigonometry, integral, multidimensional, differential calculus, plus severe time pressure to think through the answers. This is how the duel among mathematicians goes.

Math duel rules:

• two participants are given a math problem

• the first person to give the correct answer wins the round

"Participation in a math duel demonstrates the participants’ competence and their passion for higher math," say the organizers.

Congratulations to our students on the victory!
