🔍 Explanation:
To multiply a 4-digit number by a 2-digit number, we use the
standard algorithm:
1. Multiply the 4-digit number by the
ones digit of the 2-digit number.
2. Multiply the 4-digit number by the
tens digit of the 2-digit number (and shift one place to the left).
3. Add the two results.
For example, in
2,032 × 83:
- First: 2,032 × 3 = 6,096
- Second: 2,032 × 80 = 162,560
- Sum: 6,096 + 162,560 =
168,656
This method works for all problems above.
