The following quiz is a really fun challenge that requires two important capabilities: The first is to do math in your head, the second is your short term memory. We will show you a number, then you will be asked in each slide to perform a simple math operation with that number (add, subtract, multiply or divide) while choosing the right answers until you get to the correct final one! In the end, if you fail, you can find out where you went wrong and try again. Can your memory hold the math? Let's find out!

Hold the following sequence of math operations in your head, and select the number you are supposed to reach each time.

You Took a False Step

Somewhere in your calculations you went wrong, and so did not get all answers correct. Below you will see where your answers started being wrong, to see where you lost the thread. You can try again starting from that point or restart it to see if your memory can hold better this time!

Your Memory is Awesome!

Not only did you remember all the numbers in your head but you were able to perform operations on them while holding them like that, which means you have a good head for math or a good memory or both. Great job!
