Dev log: Date 8/1/26 Time 9:18am (as of posting) New functions and somethings were changed in my new version of the MathX extension… V.1.0.0! This version doesn’t add too much to it but it does revamp one category: **The Original Custom Functions Category.** I had to redesign the blocks and category since there was an issue of some Blockly stuff that MakeCode can’t do (forum link: [How to create reusable formula blocks in MakeCode extensions?](https://forum.makecode.com/t/how-to-create-reusable-formula-blocks-in-makecode-extensions/45112) ) Though, now, the blocks now work. When you’re creating you’re custom function, you must use **MY** equation/evaluation blocks, otherwise it won’t work. You can still use my other blocks too with it. If for example, you wanted for some reason a formula that you reuse to be this: `PI + Euler's Number + parameter(0) // parameter0 is whatever the player inputs ` You could do this. And also, we have **our first MathX demo project:** > **[MathX Extension TEST](https://arcade.makecode.com/S48483-30088-00291-84148)** > > This is the test for the MathX Extension --- _[View the full topic](https://forum.makecode.com/t/mathx-extension/45098)._
