Answer

Makes sense.

Work Step by Step

When adding two numbers with different signs, the sign of the sum is taken from the number with the greater absolute value, So, $-227+319$ is positive, because 319 has greater absolute value. $227+(-319)$ is negative, because $(-319)$ has greater absolute value. Since any positive number is greater than any negative, the first sum is greater. Makes sense.
