How to Multiply Whole Tens by Whole Tens Easily
FAQs on Class 3 Maths Worksheet: Multiply Whole Tens by Whole Tens
1. How do you multiply whole tens by whole tens?
Multiplying whole tens, such as 20 × 40, is a simple process that can be done in two easy steps.
- First, you multiply the non-zero digits (the numbers in the tens place). For example, in 20 × 40, you would multiply 2 × 4 = 8.
- Next, you count the total number of zeros in the original numbers (one in 20 and one in 40, making two zeros) and add them to the end of your result.
- The final answer for this multiplication of tens problem is 800.
2. What is a whole tens multiplication pattern?
The whole tens multiplication pattern is a mental math trick based on place value that simplifies multiplying numbers ending in zero.
This pattern allows you to quickly solve problems like 50 × 60. You understand that 50 is 5 tens and 60 is 6 tens. By first solving the basic fact 5 × 6 = 30 and then adding two zeros to account for the tens places, you can easily find the answer, 3000. This is a core concept in Class 3 maths multiplication.
3. What are whole tens in maths?
Whole tens are numbers that are multiples of 10, which means they always end with a zero in the ones place.
- Examples of whole tens include 10, 20, 30, 40, 50, 80, 90, and 100.
- In terms of place value, these numbers have a value in the tens place but a zero in the ones place.
- Understanding whole tens is a foundational skill for mastering 2-digit by 2-digit multiplication in later grades.
4. Why is multiplying by multiples of 10 easier?
Multiplying by multiples of 10 is easier because it transforms a complex problem into a basic multiplication fact combined with a simple rule for adding zeros.
Instead of doing long multiplication for a sum like 70 × 80, you can use a mental math strategy. You only need to solve the core fact (7 × 8 = 56) and then add the two zeros to get the final answer: 5600. This avoids complex calculation and builds confidence in multiplication for beginners.
5. What skills does this Class 3 multiplication worksheet help build?
