Your TI-83 Plus calculator provides the tools to enter and solve complex equations. For instance, you can store up to 10 matrices, which are sets of numbers or functions that are arranged in a rectangle, in the device's memory. The TI-83 Plus's limited memory, which maxes out at 160 KB, may prompt you to clear unused matrices from storage. Use the TI-83 Plus's memory management functions to remove matrices from the device.
