Ok let’s finish up this chapter by looking at this last lesson on matrix operations. You need to know basic matrix operations for the GED. The good news is that basic matrix operations are very easy however it’s easy to make mistakes. The key in all mathematical problem solving is writing neat and showing all your steps. Don’t make the common student mistake of sloppy work as it almost always results in errors.
Things to focus on in this lesson:
• scalar multiplication
• how to add and subtract a matrix
• how to simplify basic matrix operations
