Steps to Solve 3-Digit by 3-Digit Multiplication in Columns
FAQs on Multiply 3-Digit Numbers in Columns: Class 5 Maths Practice
1. How do you multiply in columns 3-digit by 3-digit?
To multiply 3-digit numbers by 3-digit numbers in columns, you use the long multiplication method which involves breaking the problem into smaller steps. This ensures all digits are multiplied correctly according to their place value.
- Step 1 (Align): Write the numbers one below the other, carefully aligning the digits in the ones, tens, and hundreds columns.
- Step 2 (Multiply by Ones): Multiply the top number by the ones digit of the bottom number. Write this first partial product below the line.
- Step 3 (Multiply by Tens): Multiply the top number by the tens digit of the bottom number. Write this second partial product below the first, adding one zero as a placeholder on the right.
- Step 4 (Multiply by Hundreds): Multiply the top number by the hundreds digit of the bottom number. Write this third partial product below the second, adding two zeros as placeholders.
- Step 5 (Add): Add all three partial products together to get the final answer.
2. What grade is 3-digit by 3-digit multiplication taught?
Multiplying 3-digit by 3-digit numbers is a key topic typically taught in Grade 5 Maths. This concept builds on earlier multiplication skills and is fundamental for mastering large number multiplication as per the CBSE and other educational board syllabuses.
3. How many steps are there to multiply a 3-digit number by a 3-digit number?
The standard column method multiplication for a 3-digit by 3-digit problem involves approximately five main steps. Following these steps ensures accuracy and proper place value alignment.
- Align the numbers vertically by place value.
- Calculate the first partial product (multiplying by the ones digit).
- Calculate the second partial product (multiplying by the tens digit, adding one placeholder zero).
- Calculate the third partial product (multiplying by the hundreds digit, adding two placeholder zeros).
- Add all the partial products to find the final result.
