find a shorter and/or different algorithm to reach the answer. 2. Unlike other technological tools, the app only provides algebraic representation and does not provide graphical or numerical representations for solving problems. This can limit the possibilities for exploration and rich mathematical discussions in the K-12 classroom. Figure 1 . Typed equation 1 solved correctly

3. When solving simple algebraic expressions using typed text, we found the app to be unstable. It would read the same expression differently on different occasions (see Figure 1 and Figure 2). We found the same problem to occur with handwritten text (See Figure 3 and Figure 4). If you use this app, or any other app in your K-12 classroom, we would like to hear from you. Figure 2 .
