Also, CC licenses require that we provide a disclaimer so we do so here: the Univeristy of Utah in no way endorses WPI's use of this content or its veracity. All errors on our website are WPI's fault. For instance, we have tried out best to put the same material into ASSISTments but errors happen. To give an example, we had a copy-paste error the other day reported where we copied the "1/2" symbol but it pasted as "12". We have corrected the errors when we have been informed about them. Also, we have made to modify the content to make it gradeable by computer. For instance we would sometime have to specify how many digits to round your answer to. But we have tried to stay as consistent with Utah Math's question as possible.
We would like to thank the authors of Utah Math and the University of Utah for releasing this free resource; many student using ASSISTments have benefits from this being free.
