AEFL = Almost Error Free Learning

AEFL is more entertaining and only a little more complex than flash cards. Each AEFL item offers 2 images, 2 response options, and immediate feedback. Difficulty increases gradually in response to the learner's progress and initiative.

In less than 10 seconds after you click the "Go to item 1 NOW!" button, you will probably finish the first sample AEFL item!

Equivalent Expressions?

In many of the AEFL 2-image items, you will see two mathematical expressions, each framed separately by a rectangle. Your task is to decide if the two expressions are equivalent or not – based on the rules of arithmetic and algebra used in most introductory algebra courses.


Each AEFL Section usually takes 4-6 minutes to complete.
