If the positive number has a bigger magnitude, the result is positive.

If the negative number has a bigger magnitude, the result is negative.

When you add a negative number, ^–3, and a positive number, 58, the result has the same sign as the number with the larger magnitude.

The magnitude of ^–3 is 3.

The magnitude of 58 is 58.
