If You Can Do 11/15 of These Math Problems in Your Head, We’ll Be Impressed!

No pen and paper allowed.

9 comments

People who are amazingly fast at solving math problems in their heads might seem smarter than other people, but that's probably not true. With the help of some mental math tricks, and practice through quizzes like this one, you can do the same too.

Being able to calculate quickly in the head will not just help you in school but in everyday life as well. Calculators are awesome, but they're not always handy. More to the point, no one wants to be seen reaching for the calculator on their mobile phone when it's time to figure out a 15 percent gratuity.

Mental math isn't as difficult as it might sound, and you may be surprised at how easy it is to make seemingly impossible calculations without a calculator, pen and paper.

Have a go at this quiz and test your mental agility for the next 10 minutes. Try to solve these math problems using nothing but your beautiful brain and see if you can get a perfect score.

    The bigger the numbers in the question, the greater the need to break them down into multiple sub-answers, which are then combined.

    Oh dear, you did not do as well as we had hoped but that’s alright. This quiz is really tough without a calculator and it is perfectly normal to miss a few questions. Good try nonetheless!

    I got 15 out of 15!
    Some of the questions I did not learn yet, and a lot of them I thought I couldnโ€™t do in my head, but I did it!
