Ok, quick - add 80 and 91, or 11 and 15. Or add another set of numbers, like 80+33 or 91+20. Can you add those up in your head? Do you find mental mathematics easy?

So you reckon then that you are a bit of a math wizard? Well, you're lucky - some of us need the calculator, even for basic two-digit number addition.

Do you remember back in school when our teachers would tell us the importance of not always relying on your calculator to do the math for you? That it would make you lazy? That you should develop your own system to help you add numbers easily? Well, hopefully, you did. There are many ways to add numbers together in our heads, it's about finding a system that works for you (and if you take this test, we will show you one or two methods that we use).

So let's get right back to the task at hand. Thirty-five questions of basic two-digit number addition. If you are good at this sort of thing, you really will fly through this test in no time at all.

Can you get 100%, though? Sometimes numbers can trick us!

Let's see how you fare! Good luck!
