Understanding the result
Example: −7 + 4 = −3: with different signs you subtract the smaller absolute value and keep the sign of the larger.
Frequently asked questions
What's the rule when both integers have the same sign? When signs match, you add the absolute values and keep that shared sign, for example −4 + −3 = −7.
How does subtracting a negative number work here? Subtracting a negative is rewritten as adding its positive opposite, so 5 − (−3) becomes 5 + 3 = 8, which the calculator shows explicitly as a sign-rewriting step.
