Long multiplication: up to 2-digit numbers
22 October 2026
Long multiplication with two 2-digit numbers can seem tricky at first, but breaking it down into small steps makes it much easier to understand. Here is a clear example to show your child how to work through each part of the calculation.
Worked example
43 × 27
First, multiply 43 by 7 (the ones digit of 27). 43 × 7 = 301
Next, multiply 43 by 20 (the tens digit of 27).
43 × 2 = 86, then add a zero to make 860
Add the two results together. 301 + 860 = 1161
The correct answer is 1161.
| Step | Calculation | Result |
|---|---|---|
| Multiply 43 by 7 | 43 × 7 | 301 |
| Multiply 43 by 20 | 43 × 2 = 86, add 0 | 860 |
| Add results | 301 + 860 | 1161 |
Now your child can spot each stage in a long multiplication question with up to 2-digit numbers. The same method works for similar questions, and they can practise these types of sums next.
