Addition and Subtraction of Relative Numbers

This section covers the fundamental rules for adding and subtracting relative numbers, with clear examples and guidelines for working with positive and negative numbers.

Definition: Relative numbers include both positive and negative numbers on a number line, with their position relative to zero being significant.

Highlight: When adding numbers with the same sign, add their absolute values and keep the common sign. When adding numbers with different signs, subtract their absolute values and use the sign of the number with the larger absolute value.

Example: (+2) + (+7) = +9 (-5) + (-8) = -13 (+2) + (-7) = -5

Vocabulary: Absolute value refers to a number's distance from zero on the number line, regardless of its sign.
