Add-ins give the calculator additional functionality. They are pre-installed on your calculator. The add-ins are 3D Graphs, Physium, Geometry, Picture Plot, Probability Simulation. Conversion was previously an add-in and is now part of the core OS from version 3.70.
If you have accidentally deleted an add-in, you can reinstall it. You will have to download it first.
You will need a Windows or Mac PC to connect to the calculator to transfer the add-ins. Full instructions are in the download.
We recommend that you update the OS before installing add-ins, if you don’t already done so. Some of the add-ins require at least OS3.30.
