You've got to remember not the specific numbers per se, but the order of the numbers, from low to high, AND their position on the screen. That's the boxes in which they were displayed.

You are started with one number. When you correctly remember the sequence and positions of the numbers, you are then given three numbers, then four, then five, and on and on.

Please don't fret. We're not about cracking complex problems. Here, you're talking about ultra simple maths problems such as: 6-2, 2+8, 7x6.

The important thing is that you think quickly. In fact the research shows that trying to solve complicated problems does not help with this sort of brain development.
