As a math person I recommend that the easiest way to remember the difference between > (greater than) and < (less than) is to think of a number line:
less than < -4 -3 -2 -1 0 1 2 3 4 > greater than
The tip of the "greater than" symbol (>) points to the right and to the progressively larger numbers. The tip of the "less than" symbol (<) points to the left and to the progressively smaller numbers.
