It looks like it gives different results depending on whether you specifically say “solve” or not. With the input “solve ln(x) + ln(x-2) = ln(15)”, it will give you a result with a “Show Steps” option. Without the word “solve”, it just gives you a number.

[…] keep too close an eye out for it. Then I read on Teaching College Mathematics and the Number Warrior that it was up, and I was pretty impressed with the screen shots. Since then, I’ve been […]

The system also can’t give steps on absolute value equations … clearly this isn’t the homework-killer just yet.
