As kids, we never understood why we needed to learn all the various subjects at school. After all, who needs math when there are calculators? However, the tools that learning math gives us don’t end with the ability to perform complicated calculations. Learning math helps us approach challenging life and puzzle problems rationally to find a clear way of achieving the right result. If you think you have these abilities, you should prepare your brain for the next challenging quiz for which you don’t need to know complicated formulas, but you do need to adopt a smart approach that’ll help you to be part of the chosen minority that can get a perfect score. Just a little warning, this isn’t going to be easy!

Math tests are hard, especially this one, which is difficult to even prepare for. However, we aren’t in school and there is no need to beg the teacher for a re-do - you can try to answer the questions again, but this time you should give them a little more thought. You may even be able to improve your score and surprise yourself with a perfect score!

Very nice!

Your mind is definitely effective when it comes to mathematical calculations and reasoning, and even if you sometimes need a calculator, the stuff you learned in school or knowledge you have naturally have certainly helped you deal with these riddles. Now you can look at your answers and see where you went wrong. We challenge you to try again and see if you can answer them right this time!

Great Job!

Wow! We didn’t think anyone would ever achieve this result, but it seems that we are dealing with a genius. You are probably an avid riddler and logic is your strong point, even more than knowledge of math and numbers. Share this test with your friends and challenge them to try and beat your score - just don’t be surprised if they don’t succeed.
