Formula:
The Partial Products method simplifies multi-digit multiplication by applying the distributive property based on place value. For two numbers, A and B, where A is the multiplicand and B is the multiplier, each place value component of A is multiplied by each place value component of B. The sum of all these individual products then yields the final product.
For example, to multiply 23 × 45:
- Multiply the ones digit of 23 (3) by the ones digit of 45 (5): 3 × 5 = 15
- Multiply the ones digit of 23 (3) by the tens digit of 45 (40): 3 × 40 = 120
- Multiply the tens digit of 23 (20) by the ones digit of 45 (5): 20 × 5 = 100
- Multiply the tens digit of 23 (20) by the tens digit of 45 (40): 20 × 40 = 800
The final product is the sum of these partial products: 15 + 120 + 100 + 800 = 1035.
