+## Patch Notes 1.0.0 pre-release 3
+Added the ability to do math operations with 4 numbers.
+### Note:
+Everything is subject to change. This means that dont expect this to be the final full release of 1.0.0 available with all the new features and tweaks.
+## Up Next:
+The reimplementation of the old features. I had to delete all the previous code (With some exceptions) to begin developing the new code. Also, I will be merging 1.0.0-dev-preview with master today on github.
