Write 30 original math problems with step-by-step solutions (algebraic equations & mathematical logic)Creative Math Problem Generation

**Description:**
> I need a mathematics teacher or problem writer to write **30 new, original problems** in English, each with a full step-by-step solution and the reason for every step.
>
> **Topics**
> - Solving equations and inequalities: which steps keep the solution set unchanged, and which can add or lose solutions (dividing by a variable, squaring, multiplying by an expression…).
> - Finding the error in a worked solution: give a solution with one wrong step; the task is to identify the step and correct it.
> - Mathematical logic at discrete-math level: converse and contrapositive, quantifiers (for all / there exists), and the structure of a proof.
>
> **Mix:** 12 solve-and-justify · 9 find-the-wrong-step · 6 logic · **3 problems outside these topics** (e.g. calculus), each marked "out of scope".
>
> **Format and time:** one Excel file (template provided). 3 days. The first 5 problems within 24 hours.
>
> **You are a good fit if** you teach mathematics or write math problems, and can write clear, justified solutions in English.
>
> **In your bid, please include:**
> 1. Proof of teaching or problem-writing experience.
> 2. A 3-line answer: *"Someone solved x² = 3x by dividing both sides by x and got x = 3. What is wrong, and what is the correct solution?"*
>
> **Rules:** The problems must be your own, not copied from a book or website. No AI tools for writing or solving; I need your own work. The material is confidential after delivery.
