Using the Partial Differences Method
Using the Partial Differences Method is a skill on Pengi from Lesson 5: Use Strategies to Subtract Decimals in enVision, Mathematics, Grade 5.
Key Concepts
To subtract using partial differences, break the second number into its place value parts (e.g., ones, tenths, hundredths). Then, subtract each part one at a time from the first number. For a problem like $5.85 2.41$, the process is: $$(5.85 2) 0.4 0.01$$.
