FAQ
What does 'multiply in parts' mean for a 1 × 2-digit problem?⌄
Students split the 2-digit number — for example, 6 × 34 = 6 × 30 + 6 × 4 = 180 + 24 = 204 — computing two simpler products before combining them.
How does multiplying in parts connect to the standard multiplication algorithm?⌄
The partial products method is the conceptual foundation of the standard algorithm — each digit multiplication in the algorithm produces one of the same partial products.
Is multiplying in parts faster or slower than the standard algorithm?⌄
For mental math, splitting into tens and ones can be faster for many students — but for pencil-and-paper work, the standard algorithm eventually becomes more efficient for large numbers.
