82 Arrow-Puffin-4_Semester-1 Maths5-Digit NumbersThe greatest four-digit number is 9999. When we add 1 to the greatest four-digit number, we get the least five-digit number.9999 + 1 = 10,000We say 10,000 in words as ten thousand. In short, it can be written as 'TTh'.10,000 is the successor of 9999. As the numbers grow bigger and bigger, the need for dividing them into groups becomes necessary so that it is easier to read the number names.The groups into which the digits are separated are called periods.%u2022 The first three digits of a number from the right i.e., ones, tens and hundreds form the ones period.%u2022 The next two digits i.e., thousands and ten thousands form the thousands period.A place value chart is used to represent numbers where digits are placed in their respective places. It helps to read and compare the numbers.Representation of 5-Digit Numbers in the Place Value ChartPeriod Thousands OnesPlace TTh Th H T ONumber 3 2 0 4 8Number name : Thirty-two thousand forty-eightNumber : 32,048Period Thousands OnesPlace TTh Th H T ONumber 4 9 8 0 5Number name : Forty-nine thousand eight hundred fiveNumber : 49,805The word hundred is derived from the word \actually means 120 and not 100.NUMBERS BEYOND 9999Let's Understand Conceptual Understanding
