-to add or subtract measurements measurements must be in the SAME units
Adding Mixed Metric Units Steps
- Group together like units
- Add like units (starting with smaller units)
- Rename and Regroup units (if you need to)
Subtracting Metric Units Steps
- Group together like units
- Rename and regroup units (if you need to)
- Subtract like units
