What is it?

To find 'ten more' than a number means adding 10 to that number. It helps us understand how numbers increase by a group of ten, which is a very important idea in Maths.

Simple Example

Quick Example

Imagine you have 5 cricket balls. If someone gives you 'ten more' cricket balls, you will have 5 + 10 = 15 cricket balls in total. It's like counting forward 10 steps from your starting number.

Worked Example

Step-by-Step

Let's find 'ten more' than the number 23.

1. Start with the given number: 23.
2. The phrase 'ten more' tells us to add 10.
3. So, we write the addition problem: 23 + 10.
4. Add the ones place: 3 + 0 = 3.
5. Add the tens place: 2 + 1 = 3.
6. Combine the results: The new number is 33.

So, ten more than 23 is 33.

Why It Matters

Understanding 'ten more' is a basic building block for addition and subtraction. It's crucial for understanding place value, larger number operations, and even mental math. This skill is used by shopkeepers calculating change, engineers designing structures, and even by you when managing your pocket money.

Common Mistakes

MISTAKE: Adding 1 instead of 10. For example, thinking 'ten more than 15' is 16. | CORRECTION: Remember 'ten more' specifically means adding the number 10, not just 1.

MISTAKE: Getting confused with 'one more'. | CORRECTION: 'One more' means adding 1. 'Ten more' means adding 10. They are different!

MISTAKE: Not changing the tens digit correctly. For example, saying 'ten more than 29' is 219. | CORRECTION: When you add 10, only the tens digit increases by 1 (unless it's a number like 95, where both tens and hundreds change). The ones digit usually stays the same.

Real World Connection

In the Real World

When you buy items at a local kirana store, the shopkeeper often adds prices quickly. If a biscuit packet costs Rs. 10 and you buy 'ten more' packets, he mentally calculates 10 + 10 + 10... which is just counting by tens. This concept is used in everyday transactions and budgeting.
