Step-by-Step Guide to Multiplying 4-Digit by 1-Digit Numbers
FAQs on Class 4 Maths: 4-Digit by 1-Digit Column Multiplication Worksheet
1. How do you multiply a 4-digit by a 1-digit number?
You can multiply a 4-digit by a 1-digit number using the column multiplication method, which organises the calculation vertically. This method is a key topic in Class 4 Maths and ensures accuracy by breaking the problem down into simple steps.
- Step 1: Write the 4-digit number above the 1-digit number, aligning them by place value.
- Step 2: Multiply the 1-digit number by the ones digit of the top number. Write down the ones part of the answer and carry over the tens part.
- Step 3: Repeat for the tens, hundreds, and thousands digits, adding any carryover digit from the previous step.
- Step 4: The final number written below the line is your answer.
2. What are column multiplication sums?
Column multiplication sums are problems where numbers are arranged vertically in columns according to their place value to make multiplication easier. This method is essential for solving multi-digit multiplication problems, such as multiplying a 4-digit number by a single digit.
- It helps keep calculations organised and reduces errors.
- It is the standard method taught in the NCERT Class 4 Maths curriculum.
- It clearly shows how carryover digits are handled from one column to the next.
3. How are carryover digits handled in multiplication?
In column multiplication, a carryover digit is created when the product of two digits is 10 or more, and it must be added to the next column's product. Handling the carryover (or regrouping) correctly is crucial for finding the right answer in 4-digit by 1-digit multiplication.
- First, multiply the digits in a column (e.g., the ones column).
- If the result is 12, you write down '2' and 'carry over' the '1' to the tens column.
- Next, multiply the digits in the tens column and then add the '1' you carried over.
- This process is repeated for all columns from right to left.
