How can I improve this?

i like what your doing tbh, this can help people if it’s needed within their code or if they don’t know the formula towards these calculations

Shame all these posts and resources I make are getting deleted or hidden. Not like a spend time on them or anything.

This is getting really frustrating. I put a lot of effort into these posts and resources, and it feels like all that work is just being undone. I know that the people who are deleting or hiding my work don’t think that it’s valuable, but it is to me. And I know I’m not the only one who feels this way.

It’s just not fair. We put so much time and effort into something, only to have it be taken away without any explanation. I know that the people who are doing this think they’re helping, but they’re not. All they’re doing is making it harder for the rest of us.

We need to find a way to stop this from happening. Maybe we can create a petition or something, to get the attention of the people who are doing this. I’m not sure what the solution is, but something needs to be done. Otherwise, all of our hard work will just keep getting deleted or hidden.

So please, if you agree with me, spread the word. Let’s try to put a stop to this. We deserve to be heard.

Thank you.

I agree with you here and disagree with the moderators who are taking them down, these posts you are making can help many people with formulas on how to find the mean, average and it will teach them actual math which they can use when they go to school, this is the thing with coding, it teaches you stuff mathematically which you can use in real life and at school aswell, I don’t think some people realise that
