- Adding signed fractions and decimals Use a common denominator for fractions and align decimal places. A minus sign before a mixed number applies to the whole value.
- Distance and displacement Signed change is end minus start. Distance is the absolute value of the change.
- Opposites and zero pairs Opposites have equal magnitudes and opposite signs. Their sum is zero.
- Signed addition on number lines Start + change = end. Positive change moves right or up; negative change moves left or down.
- Subtracting signed fractions and decimals Keep the first number and add the opposite of the second. A minus sign before a mixed number applies to the whole value.
