- Watch out for complex numbers in your data, which can not be plotted in Mathcad. Imaginary parts in your numbers leads to either incomplete graphs or errors instead of plots. To work with complex numbers, you can plot the real and imaginary parts of your numbers separately, or reframe your data to calculate only the real part before plotting.

- Matrices are challenging, but they are really important in applied mathematics – they are a critical STEM topic. Engineers and scientists use matrices to solve challenging problems in many, many dimensions. Mathcad’s matrix and graphing tools offer capabilities that can help students’ explore matrices early in their school experience so that they are both prepared to use and aware of the importance of matrices. With currently available technologies matrices can be used, explored, and visualized effectively in Algebra 1 class. Systems of equations in three variables need not be avoided any longer. Matrices can be an efficient and powerful way to solve systems, with increased clarity now that we have tools to graph 3D plots.
