What is it?

Place value tells us the worth of each digit in a number based on its position. When we talk about 'up to Crores', we are looking at the value of digits in very large numbers, following the Indian Number System.

Simple Example

Quick Example

Imagine you have Rs 500. The '5' here means five hundreds. If you have Rs 5000, the '5' now means five thousands. The digit '5' changed its value just by changing its 'place' in the number.

Worked Example

Step-by-Step

Let's find the place value of each digit in the number 7,35,42,189 (Seven Crore, Thirty-Five Lakh, Forty-Two Thousand, One Hundred Eighty-Nine).

1. Start from the rightmost digit: 9 is in the Ones place. Its value is 9 x 1 = 9.
---2. Next, 8 is in the Tens place. Its value is 8 x 10 = 80.
---3. Then, 1 is in the Hundreds place. Its value is 1 x 100 = 100.
---4. Moving left, 2 is in the Thousands place. Its value is 2 x 1,000 = 2,000.
---5. After that, 4 is in the Ten Thousands place. Its value is 4 x 10,000 = 40,000.
---6. Then, 5 is in the Lakhs place. Its value is 5 x 1,00,000 = 5,00,000.
---7. Next, 3 is in the Ten Lakhs place. Its value is 3 x 10,00,000 = 30,00,000.
---8. Finally, 7 is in the Crores place. Its value is 7 x 1,00,00,000 = 7,00,00,000.

So, the place values are 7 Crores, 3 Ten Lakhs, 5 Lakhs, 4 Ten Thousands, 2 Thousands, 1 Hundred, 8 Tens, and 9 Ones.

Why It Matters

Understanding place value is super important for handling large sums of money, like budgeting for a big family event or understanding government project costs. It's crucial for careers in finance, banking, and even for scientists who deal with very large numbers, like distances in space.

Common Mistakes

MISTAKE: Confusing face value with place value. For example, in 567, saying the place value of 5 is just '5'. | CORRECTION: Face value is the digit itself (5). Place value is the digit multiplied by its position (5 x 100 = 500).

MISTAKE: Incorrectly placing commas in large numbers, especially between Lakhs and Crores, in the Indian Number System. For example, writing 10000000 as 10,000,000. | CORRECTION: In the Indian system, commas are placed after the hundreds place (three digits from the right), and then after every two digits. So, 10000000 is written as 1,00,00,000.

MISTAKE: Forgetting that a '0' still has a place value, even if its value is zero. For example, in 4,05,123, thinking the '0' has no place value. | CORRECTION: The '0' in 4,05,123 is in the Ten Thousands place. Its place value is 0 x 10,000 = 0, but its position is still important for the overall number's value.
