Can You Do Math and Remember as Well?

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!
