How I Use It
If I used this product, it would be to provide students with an extra tool to check their work. It works if you write the problem specifically and exactly as you should. The problem is that it might misread what you want it to do and set up a problem that is nothing like what you want to answer. A simple addition problem could possibly produce a large equation with exponents and fractions.
I do not like this app because students tend to spend a lot of time setting up a problem in order to get an answer. You have to be very careful how you write the problem so you get the set up you want to get the answer you need. I believe it is a great concept but might need a little extra help to make it more effective.
