Simple Example

Quick Example

Imagine you are saving money in your piggy bank. If you have saved 1000 rupees, and then your uncle gives you another 1000 rupees, you now have a total of 2000 rupees. That's a lot of money!

Worked Example

Step-by-Step

Let's say you want to buy a new cricket bat that costs 2500 rupees. You currently have 500 rupees. How much more money do you need to reach 2000 rupees?

1. You want to reach a target of 2000 rupees.
2. You already have 500 rupees.
3. To find out how much more you need, you subtract what you have from your target: 2000 - 500.
4. First, subtract the hundreds: 20 hundreds - 5 hundreds = 15 hundreds.
5. So, 2000 - 500 = 1500.
6. You need 1500 more rupees to reach 2000 rupees.

Answer: 1500 rupees.

Common Mistakes

MISTAKE: Writing '2,000' as '200,0' or '20,00' | CORRECTION: Remember that in India, we use commas to separate thousands. So, 2000 is written as '2,000' to make it easy to read.

MISTAKE: Confusing 2000 with 200 or 20,000 | CORRECTION: Pay attention to the number of zeros. 2000 has three zeros, 200 has two zeros, and 20,000 has four zeros. Each zero adds a 'place value'.

MISTAKE: Reading 2000 as 'two hundred' | CORRECTION: 2000 is read as 'two thousand'. 'Two hundred' is 200. Always look at the place value of the first digit.
