Missing very important feature
I have purchased this App for my daughter who is unable to write, but can type. We would like it to eventually replace the need for a scribe for Math. One of the most important things she needs to do is to show the problem solving steps. In this regard, Maths exams at a higher level are graded proportionally on both the steps taken to achieve the solution as well as the final answer. Showing the workings regularly involves crossing out numbers and letters in both whole and fractional numbers. This feature is not available as far as we can see. Perhaps this can be addressed in the next update, otherwise this app will not be usable past early learning maths and a waste of $31 for anyone at a high school level.
