Addition of numbers with unlike signs: To add two real numbers that have unlike signs, subtract the smaller absolute value from the larger absolute value and associate with this difference the sign of the number with the larger absolute value.

A number is denoted as positive if it is directly preceded by a plus sign or no sign at all. To avoid any confusion between "sign" and "operation," it is preferable to read the sign of a number as "positive" or "negative." The opposite of a real number is denoted by placing a negative sign directly in front of the number.
