Since our last Math Quiz was deemed a bit easy by some of you, today we have something a bit more challenging, and it will require you to solve no less than 25 math problems. Some will be very short and some longer, some very easy and some (especially towards the end) will be quite hard. We wish you good luck!

When you fail, try try again

You failed this one. But it's not about passing or failing, it's about learning and trying again! Failing is how we learn to do better. So look up the material a bit and don't quit!

Not bad but not great

Not bad at all. You hit on the solution a little less than half the time, which is pretty good, but you can always do better! How about giving it another go? Or maybe try one of our other math quizzes to practice.

Great job - You did better than 80% of people!

Really good job, you got more points and answered more questions correctly than 80% of people taking this test. You don't have much to learn here, but have a look at those you got wrong and try to figure out why that happened.

You are the master!

Wow, are you a genius? How did you get so many correct, all in your head? You must be a math teacher or maybe someone who really likes it. We're super impressed!
