International Number System

Sixty two million eight hundred sixteen thousand five hundred fifty nine

Step 1: Group from the right: 62 | 816 | 559. Step 2: Ones period (559) = five hundred fifty nine. Step 3: Thousands period (816) = eight hundred sixteen thousand. Step 4: Millions period (62) = sixty two million. Final Answer: Sixty two million eight hundred sixteen thousand five hundred fifty nine. Check each group carefully — 816 means eight hundred sixteen, not eighty one six.

3 digits

Step 1: In the International system, we group digits from the right into sets of 3. Step 2: First period (Ones) — 3 digits: hundreds, tens, ones. Step 3: Second period (Thousands) — 3 digits: hundred thousands, ten thousands, thousands. Step 4: Third period (Millions) — 3 digits: hundred millions, ten millions, millions. Final Answer: Every period in the International system has exactly 3 digits. This is different from the Indian system where the first period has 3 digits but all other periods have only 2 digits.

560,830,416

Step 1: Break the number name into parts — Five hundred sixty million = 560,000,000. Step 2: Eight hundred thirty thousand = 830,000. Step 3: Four hundred sixteen = 416. Step 4: Combine: 560,000,000 + 830,000 + 416 = 560,830,416. Final Answer: 560,830,416. A common mistake is writing 083 as 83 and misplacing digits — always fill in the place value chart carefully to avoid missing zeros.

Thirty six lakh seventy eight thousand four hundred seventy five

Step 1: The number is 3,678,475. In the International system this is 3 million 678 thousand 475. Step 2: To convert to Indian system, regroup from the right: first 3 digits (475), then 2 digits (78), then 2 digits (36) → 36,78,475. Step 3: Now read using Indian periods — 36 lakhs, 78 thousands, 475 ones. Step 4: Number name = Thirty six lakh seventy eight thousand four hundred seventy five. Final Answer: Thirty six lakh seventy eight thousand four hundred seventy five. The key is regrouping digits using Indian period rules (3-2-2 from right).
