Congratulations! You passed the ancient Roman math test! You're basically a mathematical genius! You clearly know how to solve these problems and you're not afraid to look to solve other, more challenging ones too! You're definitely smarter than the average, and are ready to take on any numerical challenge that you may encounter down the line!
You got less than half of the questions correct. Don't feel too bad though, only 12% of the people taking this test did better than you! You better study up and retake the test soon! Good luck!
