I have been trying to figure out how best to run multiple maths operations on a list of numbers and so far I have to run the operation on 2 numbers and then use that result in the next operation and so on. Maybe the block can be changed to have a gear function that allows you to add multiple operations in the same block. ---

You’ll need to provide more details about the operation. Can you give a specific example of values you might start with and intermediate calculations? It sounds like you might need a recursive function. ---

Use blocks inside the block… like this ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/5/e5fca188b2bf20518bbf9e39d3d681903d3b91f3.png) ---

Here’s an example of a simple sum that works for any list length: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/0/80a05f00977f923d2609868a5fb2cf49fb66a0cd.png) I’m adding 0 to j to make it a numeric value (rather than a text string) but you could apply other calculations there such as 2\*j, etc. ---

Will try this. Thanks. Question is, does this follow PEDMAS principles. ---

It will depend upon how you arrange you blocks… _consider each block as a bracket …_ that’s how I got it work. Please let’s know what do you discover. ---

> [@tiny\_apps](#): > > consider each block as a bracket Yes, that’s good advice. So this: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/5/e5fca188b2bf20518bbf9e39d3d681903d3b91f3.png) would be the same as this: `(1+(1x(1+1)))` And that would follow [PEMDAS](https://www.mathsisfun.com/operation-order-pemdas.html) since the innermost blocks/parentheses are calculated first. ---
