1. The problem is to evaluate the expression with the numbers given: $-4$, $-10$, and $3$. 2. Since the user only provided numbers without an explicit operation, let's consider a common operation such as addition for demonstration: $-4 + (-10) + 3$. 3. Use the associative property of addition to group the numbers: $$(-4 + (-10)) + 3$$. 4. Calculate the sum inside the parentheses: $$-4 + (-10) = -14$$. 5. Now add the remaining number: $$-14 + 3 = -11$$. 6. Therefore, the result of adding the numbers $-4$, $-10$, and $3$ is $-11$. 7. If a different operation was intended, please specify for a precise solution.
