Step-by-Step Guide to Multiplying 1 Digit by 2 Digit Numbers
FAQs on Class 4 Maths: Multiply 1 Digit by 2 Digit Numbers Worksheet
1. How do you multiply a 1-digit number by a 2-digit number?
To multiply a 1-digit number by a 2-digit number, you use the standard column method and multiply from right to left, regrouping when necessary. The key is to handle the ones and tens places correctly.
Here are the steps:
- Write the 2-digit number on top and the 1-digit number below it, aligned to the right in the ones column.
- Multiply the 1-digit number by the digit in the ones place of the top number. Write the ones digit of the result below the line.
- If the result is 10 or more, carry over (regroup) the tens digit to the top of the tens column.
- Multiply the 1-digit number by the digit in the tens place of the top number and add the carried-over number.
- Write this final result to the left of the ones digit in the answer.
2. What is regrouping in multiplication?
Regrouping in multiplication, often called carrying, is the process of moving a value from one place value column to the next highest column. This is a crucial skill for solving 2 digit by 1 digit multiplication problems accurately.
For example, in the problem 36 × 4:
- First, you multiply the ones: 4 × 6 = 24.
- You write the 4 in the ones place of the answer.
- You regroup or carry over the 2 (representing 2 tens) to the tens column to be added in the next step.
