Calculation Challenge

The Calculation is an important part of the brain. It's a zone which determines the intelligence of the person. On each intelligence quiz, there is a part dedicated to the mental arithmetic. That means, that to increase your intellectual capacities, you must almost increase your arithmetic capacities.

The game starts with easy arithmetic questions, with low numbers and easy operations. Multiple possible solutions are suggested, but you must choose the correct one in a given lapse of time. The numbers will be bigger at each level, and the allowed response time will be lower. The levels are grouped by categories, each category is based on an operation (sum, subtraction, multiplication…) or in a number of operands (2, 3…).

You will win points depending on the number of correct answers, and in the consumed time to answer. You will win a trophy if you found the correct answer to all the operations. The sum of the points of all the levels will give you your total score. Compare it with your friends. Who is smarter?
