Correct. The addends have different signs. So find the difference of their absolute values: $\displaystyle{86}-{28}={58}\usepackage{cmbright}\Huge\$ . Since $\displaystyle{86}>{28}\usepackage{cmbright}\Huge\$ , the sum has the same sign as $\displaystyle-{86}\usepackage{cmbright}\Huge\$ . So the answer is negative.
