The question asks you to add the numbers with different signs, specifically:

$-3 + 1$

Steps to Solve:

1. Identify the operation: You are adding numbers of opposite signs (negative and positive).
2. Subtract their absolute values: $|-3| - |1| = 3 - 1 = 2$
3. Determine the result's sign: Since the negative number (-3) has the larger absolute value, the result is negative.

Final Answer:

$-3 + 1 = -2$
