1. Problem Description

The problem requires us to write an expression for a sequence of operations. First, add 5 to 3, and then add 10 to the result. We are instructed not to simplify the expression.

2. Solution Steps

The first operation is to add 5 and

3. This can be written as $5 + 3$.

Then we add 10 to the result of the first operation. Since we don't want to simplify, we use parentheses to group the first operation, and then add 10: $(5 + 3) + 10$.

3. Final Answer

(5 + 3) + 10
