1. The problem is to compose a mathematical expression or equation without providing the answer. 2. In algebra, composing an expression means writing it down using variables, constants, and operations without simplifying or solving it. 3. For example, if asked to compose an expression for the sum of a number $x$ and 5, we write: $$x + 5$$ 4. If asked to compose an expression for the product of 3 and the difference between $y$ and 2, we write: $$3(y - 2)$$ 5. The key is to clearly represent the relationship or operation without evaluating or simplifying. 6. This approach helps in setting up problems before solving them. This completes the explanation on composing expressions without answers.
