About Partial Products
Partial products are intermediate results obtained when multiplying numbers using the standard multiplication algorithm. Each digit of the multiplier is multiplied by the multiplicand, and the results are added together to get the final product.
How it works:
- Break down the multiplier into its place values
- Multiply the multiplicand by each place value
- Add all partial products to get the final result
Example:
| Multiplication | Partial Products | Final Result |
|---|---|---|
| 23 × 45 |
23 × 40 = 920 23 × 5 = 115 |
920 + 115 = 1,035 |
| 123 × 456 |
123 × 400 = 49,200 123 × 50 = 6,150 123 × 6 = 738 |
49,200 + 6,150 + 738 = 56,088 |
